Answer:
see explanation
Step-by-step explanation:
(a)
To evaluate f(5) substitute x = 5 into f(x), that is
f(5) = 2(5) - 1 = 10 - 1 = 9
(b)
To evaluate g(x - 2) substitute x = x - 2 into g(x), that is
g(x - 2)
= (x - 2)² + x - 2 + 1 ← expand (x - 2)² using FOIL
= x² - 4x + 4 + x - 2 + 1 ← collect like terms
= x² - 3x + 3
Hey it’s me again lol.
Part a)
f(5) is inserting 5 into f(x) where x=5
(2•5) -1 = 9
Part B)
g(x-2) is inserting x-2 into g(x) where x =x-2
(x-2)^2 + x-2 + 1 = x^2 -4x +4 + x - 2 + 1
= x^2 -3x + 5
