If f(x)=x+7 and g(x)=1/x, what is (f•g)(x)?

Step-by-step explanation:

(f•g)(x) = f(g(x)) = f(1/x) = 1/x +7

2. You're given a function that maps 1 to 1, 0 to 0, and 2 to -1. The domain is the set of points that are given to the function as inputs, {1, 0, 2}, which is equivalent to the set listed in option C.

3. Evaluate at :

so the answer is B.

6. Each trapezoid in the chain contributes a copy of 8 and 6 (a total of 14), so that we should expect the total perimeter to contain . The remaining two sides contribute a constant 10 regardless of . So the perimeter is given by the formula in D, .
