Use the quadratic function f(x) = 2x^2 + 4x - 15. find any x intercepts.

So for this function we will be using the quadratic formula, which is , to solve. a = x^2 coefficient, b = x coefficient, and c = constant. Using our equation, we can solve for the zeros (x-intercepts) as such:

In short, your x-intercepts (rounded to the hundredths) are (1.92,0) and (-3.92,0).

x = 12

y = 1

for the points!

answer is  

d.

a circle

i got it down for you chief.
