1-2
5: f(x) = 5; x =
141
Х

1:31
15
4
10
119
10
12.
6: h(x) = 4; X =
f(x)
IN
7: f(4) + (4)
2
3
14
5
16

Answer 1

1. f(2) = 5

2. h(0) = 15

3. f(0) = 2

4. f(3) = 4

5. f(x) = 5; x = 2

6. h(x) = 4; x = 1

7. f(4) + h(4) = 3 + 10 = 13

Explanation:

f(x) means find the y-value at x.

for example:

f(3) means find the y-value at x=3 on the graph. the answer would be 4. you can also look at it like (3,?).

h(x)= 4 means that the y-value is 4, so you need to look at the table and find the x-coordinate that corresponds with h(x)=4
