Question

What are the x-intercept(s) of the graph of y − 3 = x^2 + 4x?

a.(−3, 0) and (−1, 0)

b.(3, 0) and (1, 0)

c.(−3, 0) and (1, 0)

d.(3, 0) and (−1, 0)

Answer 1

for x intercept put y= 0

we get -3= x^2+4x
x^2+4x+3=0
(x+1)(x+3)=0

Therefore (-1,0) and (-3,0) are the x- intercepts.

The answer is a
