Question

For the function, find f(-2), f(-0.5), and f(3).

f(x) = -x + 4
A. 2, 4.5, 1
B. 6, -4.5, 1
C. 2, 4.5, 7
D. 6, 4.5, 1

Answer 1

To find values of the function, we substitute x with the given numbers and calculate. The results for f(-2), f(-0.5), and f(3) are 6, 4.5, and 1 respectively, which match option B.

Step-by-step explanation:

To find f(-2), f(-0.5), and f(3) for the given function f(x) = -x + 4, we simply substitute each value for x into the function and solve.

For f(-2):

f(-2) = -(-2) + 4 = 2 + 4 = 6

For f(-0.5):

f(-0.5) = -(-0.5) + 4 = 0.5 + 4 = 4.5

For f(3):

f(3) = -(3) + 4 = -3 + 4 = 1

Therefore, the answers are 6, 4.5, and 1, which correspond to option B.
