Question

for f(x) = 4x+1 and g(x) =x^2-5 find (f times g) (4)

apex

Answer 1

Answer:

$(f o g)(4) =  45$

Step-by-step explanation:

Step 1:-

Given f(x) = 4 x+1 and g(x) =x^2-5

$(f o g )(x) = f(g(x))$

Given

$(f 0 g)(4)=f(g(4))$

$f(g(4))=f(4^{2}-5)=f(11)$

$f(11)=4(11)+1 = 45$

Therefore $(f o g)(4) =  45$
