PLEASE HELP problem is in the picture, algebra 2 will mark BRAINLIEST

a) x^(2) + 2x + 1

b) x^(2) + 1

c) 16

d) 1

Step-by-step explanation:

f(x) = x^(2)

g(x) = x + 1

a)

f(g(x))

input g(x) into f(x)

f(x+1) = (x+1)^(2)

= x^(2) + 2x + 1

b)

g(f(x))

input f(x) into g(x)

g(x^(2))

x^(2) + 1

c)

f(g(3))

Use the equation found in part a, substitute in 3 for x

(3)^(2) + 2(3) + 1

= 9 + 6 + 1

= 16

d)

Use the equation found in part a, substitute in 0 for x

(0)^(2) + 2(0) + 1

= 0 + 0 + 1

= 1
