X intercept is when the line crosses the x axis aka when y=0
see if you can solve for x if you set y=0
if you get a false statement, then there is no yint
we can see that A and C have xints
test B and D
B.
0=-x^2+2x+5
if we put into quadratiic formula we get an x value
D. 0=x^2-2x+5
if we put into quadratic formula, there is not x intercept
D is answer
