Question

Find f(g(2)) simplify completely f(x)= 6x+9 g(x)=3x

Answer 1

f(g(2)) = 45

Step-by-step explanation:

• f(x) = 6x + 9
• g(x) = 3x

Finding g(2)

• g(2) = 3(2)
• g(2) = 6

Solving f(g(2))

• f(g(2))
• f(6)
• f(6) = 6(6) + 9
• f(6) = 36 + 9
• f(6) = 45
• f(g(2)) = 45

Answer 2

45

Step-by-step explanation:

Given:

f(x)= 6x+9

g(x)=3x

Go from right to left in such function questions

⇒ f(g(2))

⇒ f(3(2))

⇒ f(6)

⇒ 6(6) +9

⇒ 36 + 9

⇒ 45
