The given function is:
s(f) = (4/5)x - 2
To evaluate the function when x = -3, 0, and 2, we substitute each value of x into the function and simplify:
When x = -3:
s(f) = (4/5)(-3) - 2
s(f) = -2.4 - 2
s(f) = -4.4
When x = 0:
s(f) = (4/5)(0) - 2
s(f) = -2
When x = 2:
s(f) = (4/5)(2) - 2
s(f) = 0.8 - 2
s(f) = -1.2
Therefore, s(f) is equal to -4.4 when x = -3, s(f) is equal to -2 when x = 0, and s(f) is equal to -1.2 when x = 2.
