=
Step-by-step explanation:
means the inverse function
to find an inverse function, flip the x and y variables and solve for y
f(x) = 5x^3 - 6
y = 5x^3 - 6
x = 5y^3 - 6
x + 6 = 5y^3
(x + 6)/5 = y^3
= y
Answer:
A. 0.72
Step-by-step explanation:
When the ball hits the ground, h = 0.
0 = -16t² + 6t + 4
0 = 8t² − 3t − 2
Solve with quadratic formula:
t = [ 3 ± √(9 − 4(8)(-2)) ] / 16
t = (3 ± √73) / 16
t = 0.72
