Question

How many times does the graph of the function below intersect or touch the x-axis? y = -2x^2 + 3x + 5

Answer 1

1

Answer 2

You need to find the discriminate of y=ax^2+bx+c which is b^2-4ac.
Lets call the output D..
If D is positive then you have two intersections.
If D is negative then you have none.
If D is zero then you have one.

Answer 3

put y=0 and find the discriminant ,if
\[Disc > 0 then ~the ~graph` cuts~ or~ meets y~axis~at~two~points\]
if Disc.=0 ,cuts only at one point.
if Disc<0,do not cut.
