A.
If you solve it all out you get f(x)= -4x^2 -56x-202
Answer:
∅ = 42°
Step-by-step explanation:
90 - 48 = 42° because 48 and 42 are complimentary angles (add up to 90°)
because the radii lines form an isosceles triangle, ∠∅ also = 42°
Recognizing that the dotted line is sin(x) and solid line is cos(x), it's clear to see that the sin(x) has a larger amplitude than cos(x). So, we get a1 > a2.
Only B and E satisfies the above. But E is clearly incorrect since amplitude cannot be less than 0.
Therefore, B would be the correct choice.
