D.
(-3a²b³)(4ab²)
(-3*4)(a²*a)(b³*b²)
(-12)(a³)(b⁵)
To find the inverse of this function, we need to perform some steps.
f(x) = 2x + 9
Replace f(x) with y.
y = 2x + 9
Swap x and y.
x = 2y + 9
Solve for y.
Subtract both sides by 9.
x - 9 = 2y
Divide both sides by 2.
(x - 9)/2 = y
Replace y with f^-1(x)
<h3><u>f^-1(x) = (x - 9)/2</u></h3>
