For f(x)=4x+1 and g(x)=x^2 - 5, find (fog)(4)

( fog ) ( 4 ) = 45

Step-by-step explanation:

Given function are f(x) = 4x + 1

and g(x) = x² - 5

We have to find the value of ( fog ) (4)

Since ( fog ) (x) = f [g(x)]

= 4 (x² - 5) + 1

= 4x² - 20 + 1

= 4x² - 19

Now ( fog ) (4) = 4(4)² - 19

                       = 4 × 16 - 19

                       = 64 - 19

                       = 45

( fog ) ( 4 ) = 45 is the answer.
