2x+3x^2/3
Find the x-value of all points where the function below has any relative extrema.

the answer is

d.

5.3066 m2

step-by-step explanation:

-3.5 is the distance.

i've had this question so choose the one in the absolute value sign.

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
