Graph of the polynomial x^2-3x-10


To draw the graph of the polynomial x^2-3x-10, we need to follow the steps given below:

Step 1: Find the x-intercepts or zeros of the polynomial


To find the zeros of the polynomial, we need to set the polynomial equal to zero and solve for x.

x^2-3x-10 = 0

To solve this quadratic equation, we can factor it as:

(x-5)(x+2) = 0

This gives us two solutions: x=5 and x=-2.

So, the x-intercepts or zeros of the polynomial are (5,0) and (-2,0).

Step 2: Find the vertex of the parabola


The vertex of the parabola is the point where the curve changes direction. The x-coordinate of the vertex can be found using the formula:

x = -b/2a

where a=1, b=-3, and c=-10 (from the original polynomial).

So, x = -(-3)/(2*1) = 3/2.

The y-coordinate of the vertex can be found by plugging in x=3/2 into the original polynomial:

y = (3/2)^2 - 3(3/2) - 10 = -29/4

So, the vertex of the parabola is (3/2, -29/4).

Step 3: Plot the points on a coordinate plane and draw the parabola


Using the x-intercepts and vertex, we can plot the points on a coordinate plane and draw the parabola. The axis of symmetry is a vertical line that passes through the vertex.

The graph of the polynomial x^2-3x-10 is shown below:



The axis of symmetry is the vertical line x=3/2.

Therefore, the zeros of the polynomial are (5,0) and (-2,0), and the axis of symmetry is x=3/2.
