If f(x) = x ^ 2 - 1 and g(x) = |2x + 3| then fog(3) = gof(- 3) =a) 714...
Given Functions:
- \( f(x) = x^2 - 1 \)
- \( g(x) = |2x + 3| \)
Finding fog(3):
- First, we need to find g(3) by substituting x = 3 into the function g(x).
- \( g(3) = |2(3) + 3| = |6 + 3| = |9| = 9 \)
- Next, we substitute g(3) into the function f(x).
- \( f(g(3)) = f(9) = 9^2 - 1 = 81 - 1 = 80 \)
- Therefore, fog(3) = 80.
Finding gof(-3):
- First, we need to find f(-3) by substituting x = -3 into the function f(x).
- \( f(-3) = (-3)^2 - 1 = 9 - 1 = 8 \)
- Next, we substitute f(-3) into the function g(x).
- \( g(f(-3)) = g(8) = |2(8) + 3| = |16 + 3| = |19| = 19 \)
- Therefore, gof(-3) = 19.
Conclusion:
- Therefore, fog(3) = 80 and gof(-3) = 19.
