If a question asks you to find f(2), what does that mean?

• Let x = 2

• Let y = 2

Evaluate g(a)=a+2 Find g(-2a)

• 1 + a

• -2a + 2

• 3a + 2

• -a + 2

f(a) = -4a - 5, find f(-3)

• 12a +15

• -8a - 15

• 16a - 5

• -5 - 4/3a

g(n) = 2n +1 Find g(n-1)

• -8n + 1

• 2n - 1

• 2n -7

• 5 - 2n

g(x) = 3x + 3 Find g(x-1)

• 3x - 3

• 9x - 3

• -12x - 3

• 3x

f(x) = 12x +5 Find f(x+2)

• 12x + 29

• 12x +7
