Answer:
Step-by-step explanation:
⟾Collect like terms
- 8x - 10x = x - 45
⟾Move the variable to the left
- - 2x = x - 45
⟾Collect like terms again
- - 2x - x = - 45
⟾Divide both sides by -3
- - 3x = - 45
⟾ x = 45 ÷ 3
- x = 15.

Answer:
f(-2) = -1
f(0) = -5
f(4) = -1
Step-by-step explanation:
The number inside of f( ) is telling you which equation to use to get the answer.
Example:
f(-2) since -2 is less than 0 you would use (x^2) - 5. So, ((-2)^2) - 5 = 4-5 = -1
f(0) since 0 is less than or equal to 0 you would use (x^2) - 5 again. So, ((0)^2) - 5 = 0-5 = -5
f(4) since 4 is grater than 3 you would use (2^(x-1)) - 9. So, (2^(4-1)) - 9 = -1
