Find the vertex of the parabola.
y = 2x² + 20x+46
a. (-4,-5)
b. (5, 4)
c. (-5, -4)
d. (4,5)

Imma just use calculus for this because this is in the college math section.

f’(x) = 4x + 20;
0 = 4x + 20;
x = -5;
Plug -5 into first equation
y = 2(-5)^2 + (-5*20) + 46;
y = 50 + (-100) + 46;
y = -4;

ANSWER: (-5,-4)

I’ll you if you answer my questions!

I'm just guessing, but my answer would c. 0 to 300.
