Answer:
f(x) and g(x) have the same x-intercepts (is <em>not true</em>)
Step-by-step explanation:
g(x) is a reflection across the y-axis and a horizontal compression of f(x). In general those transformations will move the x-intercepts. (The y-intercept and the number of x-intercepts will remain unchanged.)

<em>Comment on the question/answer</em>
f(x) = x^3 is a 3rd degree polynomial. When transformed to g(x) = -8x^2, its only x-intercept (x=0) remains the same. The answer above will not apply in any instance where the only x-intercept is on the line of reflection. (The question is flawed in that it does not make any exception for such functions.)

The correct answer is C. :)
Answer: 117cm^2
Step-by-step explanation:
Arectangle = L*W
= 54cm^2
Atrapezoid = 1/2 (a+b) (h)
= 1/2 (15+6) (6)
= 1/2 (21) (6)
= 1/2 (126)
= 63cm^2
