(PLEASE HELP!!) Jamal is solving the equation 2x2+7x−5=0 with the quadratic formula.

Which values could he use for a, b, and c?

a = -2, b = -7, c = 5

a = 2, b = 7, c = -5

a = 2, b = -7, c = -5

a = 2, b = 7, c = 5

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
