Find each function value. f(9) if f(x)=5x-16

If f(x) = 5x - 16, then value of f(9) is 29

Solution:

Given function is f(x) = 5x - 16

We are asked to find the value of f(9)

To find the value of f(9), we have to substitute x = 9 in given function and solve the function

Therefore, substitute x = 9

f(x) = 5x - 16

f(9) = 5(9) - 16

Multiply 5 with 9 which gives 45

f(9) = 45 - 16

Subtract 16 from 45

f(9) = 29

Thus value of f(9) is 29
