Question

Given that the f(x)= x^2 -a and g(x)= x+b find an expression for fg(x) in terms of a and b who ever gets the answer correct will be marked the brainliest and will be sent a thank you everyday.

Answer 1

Answer:

Step-by-step explanation:

f(x) = x² - a

g(x) = x + b

f(g(x)) = (x+b)² - a

   f(g(x)) = x² + b² + 2xb - a
