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 f(x)=1/2x-3 for each value of x, we substitute each value into the function and simplify:

(a) f(-8) = (1/2)(-8) - 3 = -4 - 3 = -7

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

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

(d) f(10) = (1/2)(10) - 3 = 5 - 3 = 2

Therefore, the values of the function for each value of x are:

(a) f(-8) = -7

(b) f(0) = -3

(c) f(3) = -1.5

(d) f(10) = 2
