Question

What are the x- and y-intercepts of the graph of y = 2x2 + 6x + 4?

Answer 1

im guessing that is suppose to be 2x^2 ?

you need to factor
(2x+2)(x+2)=y
put x=0 into the equation y=4
Intercept of x axis occurs when y=0
2x+2=0
so there's 2 x-axis intercepts: at x= -1 or x= -2
your answers for x and y intercepts are:
(0,4), (-1,0) and (-2,0)
