Question

If f(r) = 4 - r, what is the value of f(-6)?
a) -10
b) -2
c) 10
d) 2

Answer 1

By substituting -6 into the function f(r) = 4 - r, we find that f(-6) equals 10, making option c) the correct answer.

Step-by-step explanation:

The student has asked about finding the value of a function f(r) for a specific value of r. To find the value of f(-6) when f(r) = 4 - r, we substitute -6 for r in the equation:

f(-6) = 4 - (-6) = 4 + 6 = 10.

So, the value of f(-6) is 10, which corresponds to option c) 10.
