Answer:

  • f(-3) = 30
  • f(1) = 8
  • f(0) = 8
  • f(-5) = 60

Explanation:

Values of x less than or equal to -3 will use the first definition:

f(x) = x^2 -7x = x(x -7)

Using this, we find ...

f(-3) = (-3)(-3 -7) = 30

f(-5) = (-5)(-5 -7) = 60

__

Values of x between -3 and 3 will use the second definition:

f(1) = 8

f(0) = 8

So, the function values of interest are ...

  • f(-3) = 30
  • f(1) = 8
  • f(0) = 8
  • f(-5) = 60
