Answer:
Step-by-step explanation:
f⁻¹(x) is the inverse of f(x).
y = 4x − 9. To find the inverse, switch x and y and solve for y.
x = 4y − 9
x + 9 = 4y
y = (x + 9) / 4
So the inverse function is:
f⁻¹(x) = (x + 9) / 4
The answer is A. -7/40.
1. Make sure the (the denominators) are the same
2. Subtract the (the numerators). Put the answer over the same denominator.
