Answer 1

The numeric values for the function are given as follows:

a) f(-5) = 14.

b) f(0) = 10.

c) f(5/2) = 8.

d) f(5a) = -4a + 10.

e) f(5a - 15) = -4a + 22.

How to find the numeric value of a function?

To find the numeric value of a function, we replace each instance of the variable by the desired value.

For this problem, the function is given by:

f(x) = -0.8x + 10.

Hence the numeric values are given as follows:

• f(-5) = -0.8(-5) + 10 = 14.

• f(0) = -0.8(0) + 10 = 10.

• f(5/2) = f(2.5) = -0.8(2.5) + 10 = 8.

• f(5a) = -0.8(5a) + 10 = -4a + 10.

• f(5a - 15) = -0.8(5a - 15) + 10 = -4a + 22.
