Afunction is shown. f(x) = -3*4^x what is the value of x when f(x) = −48?

x=2

Step-by-step explanation:

Step 1: Flip the equation.

−3(4x)=−48

Step 2: Divide both sides by -3.

−3(4x)

−3

=

−48

−3

4x=16

Step 3: Solve Exponent.

4x=16

log(4x)=log(16)(Take log of both sides)

x*(log(4))=log(16)

x=

log(16)

log(4)

x=2
