Question

Evaluate f (x) = 1/2X - 3 for each value of x. Show your work.

(a) f(-8)
(b) f (0)
(c) f (3)
(d) f (10)

Answer 1

To evaluate the function f(x) for different x-values, substitute each value into the function and simplify. The results are f(-8) = -7, f(0) = -3, f(3) = -1.5, and f(10) = 2.

Step-by-step explanation:

To evaluate the function f(x) = 1/2x - 3 for each given value of x, we simply substitute the value of x into the function and calculate the result. Below are the evaluations for each provided x-value:

• f(-8): Substitute x with -8 to get f(-8) = (1/2)(-8) - 3 = -4 - 3 = -7.
• f(0): Substitute x with 0 to get f(0) = (1/2)(0) - 3 = 0 - 3 = -3.
• f(3): Substitute x with 3 to get f(3) = (1/2)(3) - 3 = 1.5 - 3 = -1.5.
• f(10): Substitute x with 10 to get f(10) = (1/2)(10) - 3 = 5 - 3 = 2.

Answer 2

f(-8) = (1/2)(-8)-3 = -7

f(0) = (1/2)(0)-3 = -3

f(3) = (1/2)(3) -3 = -1.5

f(10) = (1/2)(10) -3 = 2
