Question

Use the discriminant to determine how many x-intercepts the graph of the equation has.

y = – 4x2 + 3x + 2

A. zero
B. one
C. two
D. three

Answer 1

discriminant = b^2 - 4ac

the a , b and c are the coefficients in
ax^2 + bx + c

Answer 2

so for your equation a = -4

Answer 3

the sign of the discriminant ( or if = 0) will tell you about the nature of the x-intercepts

Answer 4

- and number of intercepts of course

Answer 5

If discriminant > 0 there are 2 intercepts
= 0 there is only one
< 0 there are no intercepts

Answer 6

thank you so much @welshfella
