Inverse function of
f(x)=4x

F(x)= 4x

y=4x

now, switch the variables

x= 4y

simplify the equation so that y is by itself. Divide each side by 4

x/4= y

or f(x)= x/4 is the answer

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)
