Final answer:
The student is given the function f(x) = 5 - 2x and asked to calculate the values for f(-9), f(0), f(2), and f(-9) again. By substituting the appropriate values into the function, the answers are (a) 23, (b) 5, (c) 1, and (d) 23.
Step-by-step explanation:
The student is asking to find the values of the function f(x) = 5 - 2x for different values of x. Here, we will evaluate the function at the given points.
- f(-9): Substitute x with -9,
f(-9) = 5 - 2(-9) = 5 + 18 = 23. - f(0): Substitute x with 0,
f(0) = 5 - 2(0) = 5. - f(2): Substitute x with 2,
f(2) = 5 - 2(2) = 5 - 4 = 1. - f(-9) again, as this is most likely a duplication mistake, but we use the previous calculation to give the answer,
f(-9) = 23.
For each part, the answers are: (a) 23, (b) 5, (c) 1, (d) 23.
