Question

Find the value of f(5) for each function

1. f(x) = -2(x+1)
2. f(a) = 3(a +2)-1
3. f(h) =- h/10
4. f(m) = 1 - 4 (m/2)
5. f(m) = 2(m-3)

Answer 1

1. -12

2. 20

3.-1/2

4. -9

5. 4

Explanation:

1. -2(5+1) = -12

2. 3(5+2)-1 = 21-1 = 20

3. -5/10 = -1/2

4. 1-4(5/2) = 1-20/2 = 1-10 = 9

5. 2(5-3) = 4
