Answer:
C)
Explanation:
The highest point on the graph for c) is in the first quadrant (where x=2 would be).
If you had an equation, you would be able to find critical points on the function by setting the numerator and denominator equal of f'(x)=0 and solve. You'd have to evaluate f(x) at these critical points and end points to figure that out. This is, if you're in calculus and you would ever need assistance otherwise!
