Question

If f (x) = x square + 2 and g(x)= 5x-8 then f+g(1)=

Answer 1

SOLUTION:-

Algebra of Function

f(x) = x² + 2

g(x) = 5x - 8

Then

(f + g)(x) = f(x) + g(x)

•°• (f + g) (x) = x² + 2 + 5x - 8

•°• (f + g) (1) = (1)² + 2 + 5(1) - 8

= 1 + 2 + 5 - 8

= 8 - 8

= 0

Answer.

=> (f + g) (1) = 0
