Based on the graph,

f(-3)

f(-3) = 0

2. f(4)

f(4) = -3

3. x when f(x) = 5

f(x) = 5
x = 0

4. x when f(x) = -3

f(x) = -3
x = ±4

0.5y/4/9=y+3/8

PIT_PIT [208]

Step-by-step explanation:

The question needs to be more specific. But assuming it is 0.5y/(4/9), I will solve it.

This would make it 4.5y/4 =y + 3/8

- Multiply 4 to both sides

4.5y = 4y + 12/8

- Subtract 4y to both sides

0.5y = 12/8

- Divide both sides by 0.5

y = 3

Now plug in to check.

0.5(3)/(4/9)=3+3/8

Both equals 3.375!
