if f(x)= 5x + 4 and g(x) = 1/2x

find ,
a) fg(5)

Sagot :

Answer:

f(g(5)) = 16.5

Step-by-step explanation:

To calculate f(g(5)), evaluate g(5) then substitute the value obtained into f(x)

g(5) = [tex]\frac{1}{2}[/tex] × 5 = 2.5 , then

f(2.5) = 5(2.5) + 4 = 12.5 + 4 = 16.5

Answer: fg(5) = 16.5

Explanation:

g(5) = 1/2 × 5

= 2.5

f(2.5) = 5(2.5) + 4

= 12.5 + 4

= 16.5
