The table above gives values of the quadratic function f for selected values of x. Which of the following defines the quadratic function f?
  • a)
    f (x) = x2 - 6
  • b)
    f (x) = x2 + 6
  • c)
    f (x) = 2x2 - 10
  • d)
    f (x) = 2x2 - 6
  • e)
    f (x) = 2x2 - 7

The table above gives values of the quadratic function f for selected ...
To solve this problem, substitute the given values for x into each function to see if you get the correct value for f (x). Answer choice A is correct because for each of the four given x values, x2 - 6 yields the correct f (x) values.

Directions: Read the passages and choose the best answer to each question.PassageA chemical bond is the physical phenomenon of chemical substances being held together by attraction of atoms to each other through both sharing and exchanging of electrons or electrostatic forces. Bond energy is a measure of bond strength in a chemical bond. For example, the carbon hydrogen (C–H) bond energy is the energy change involved with breaking up the bond between the carbon and hydrogen atoms. Bonds with a higher energy release more energy when they form, and are considered to be more stable (less reactiv e).When reacting with nonmetals, hydrogen forms covalent bonds, meaning that the bonded atoms share electrons with each other. Figure 1 shows the bond energies and distances for bonds involving hydrogen and nonmetals (H–X). The chart is arranged by period (rows of periodic table); in addition, the values for group 17 (column 17 on the periodic table) are compared.Bond length is the distance between two bonded atoms in a molecule. Bond lengths are measured in molecules by means of X-ray diffraction. A set of two atoms sharing a bond is unique going from one molecule to the next. For example, the oxygen to hydrogen bond in water is different from the oxygen to hydrogen bond in alcohol. It is, however, possible to make generalizations when the general structure is the same. Figure 2 relates bond energy to bond length for H–X bonds between hydrogen and nonmetals. The elements in each period or group are connected by a line (with the exception of the first, which contains only hydrogen).Q.Suppose a certain experiment calls for a very stable substance with bond energy greater than 420 kJ/mol.Which of the following pairs of elements in a compound would yield a stable enough substance?

Directions:Read the passages and choose the best answer to each question.PassageSeveral scientists considered some different environmental factors and their influence on the growth of certain bacteria. The following experiments used Salmonella bacteria to measure the effect of pH levels, nutrients, and temperature on the number of bacteria produced within a given time period.Experiment 1A known quantity of Salmonella bacteria was placed in each of 3 Petri dishes with the same nutrient concentration at the same temperature. The pH level of each nutrient concentration in each dish was varied according to Table 1. On the pH scale, 7 represents neutral, values less than 7 indicate an acid, and values greater than 7 indicate a base. The lids of the Petri dishes were replaced after the bacteria were added and the dishes were left alone. After 6 hours, the percent growth of Salmonella bacteria was recorded (Table 1).Experiment 2A known quantity of Salmonella bacteria was placed in each of 3 Petri dishes with different nutrient concentrations in the form of organic compounds. The temperature and pH level (neutral 7) were held constant in each sample.The lids of the Petri dishes were replaced after the bacteria were added and the dishes were left alone. After 6 hours, the percent growth of Salmonella bacteria was recorded (Table 2).Experiment 3A known quantity of Salmonella bacteria was placed in each of 3 Petri dishes at different temperatures. The pH level and nutrient concentrations were held constant. The lids of the Petri dishes were replaced after the bacteria were added and the dishes were left alone. After 6 hours, the percent growth of Salmonella bacteria was recorded (Table 3).Q.Which of the following conclusions is strengthened by the results of Experiment 1?
