Question

PLEASE HELP!! URGENT! What is f[g(3)] for the following functions? f(x) = 4x2 − 3 g(x) = 5x − 2 A. f[ g(3) ] = 13 B. f[ g(3) ] = 163 C. f[ g(3) ] = 363 D. f[ g(3) ] = 673

Answer 1

f[g(3)] = 673

Explanation:

I took the test

Answer 2

`\boxed{f[ g(3) ] = 673}`

Explanation:

`f(x) = 4x^2 - 3 \\ g(x) = 5x - 2`

`f(g(3))`

`f(5(3)-2)`

`f(15-2)`

`f(13)`

`f(13)=4(13)^2 -3`

`f(13)=4(169) -3`

`f(13)=676-3`

`f(13)=673`
