Question 278295: Put the function into factored form with integer coefficients and then identify any horizontal intercepts. [Give exact answers in form of fraction. Write your points in ascending order of its x-coordinates. If there is only one horizontal intercept, put the same coordinates for both points.] y=4x^2-3x-7

Put the function into factored form with integer coefficients and then identify any horizontal intercepts. [Give exact answers in form of fraction. Write your points in ascending order of its x-coordinates. If there is only one horizontal intercept, put the same coordinates for both points.] y=4x^2-3x-7
----
y = 4x^2 -7x+4x -7
y = (x(4x-7) + 4x-7
y = (4x-7)(x+1)
-------
There are two horizontal intercepts: x = -1 and x = 7/4

The graph looks like:
