EASY MEDAL

Answer 1

How many x-intercepts does the graph of the given equation have?

Use the discriminant.

y = -4x^2 + 3x + 2


A. 0

B. 1

C. 2

D. 3

Answer 2

It's sqrt(b^2-4ac) where "a" is the x^2 coefficient, "b" is the x-term coefficient, and "c" is the last term.

So a=-4, b=3, and c=2.

Just plug these values into the equation above and solve.

Answer 3

So what is the answer?

Answer 4

Wait... just plug the a,b,c values into this b^2-4ac (I took out the sqrt)

Answer 5

If the answer is positive there are 2, answer is 0 then there is 1, and if the answer is negative there are no x-intercepts.

Answer 6

So it's 0?

Answer 7

Answer 8

No the answer is 2. What is 3^2-4(-4)(2)?
