<h2>Question 1:</h2>

T(-4) = -(-4) - 2

-(-4) - 2 = <em><u>2</u></em>

To evaluate a function at a given input, you have to substitute every occurrence of the variable with that particular value.

So, for the first function, you have

T(x) = -x-2 \implies T(-4) = -(-4)-2 = 4-2 = 2

The name of the variable is obviously irrelelvant, so the same goes for the second function:

w(x) = 14-6x \implies w(-3) = 14-6\cdot(-3) = 14 + 18 = 32
