Question

Please help I will give brainliest.

Answer 1

A y-intercept is a coordinate with its x-coordinate equaling zero

• First question: has a negative y-intercept

            $y= x^2+3x -2=0^2+3(0)-2=-2$

• Second question: y-intercept isn't positive or negative

            $y = x^2-10x= 0^2-10(0) = 0$

• Third Question: y-intercept is positive

            $y = (x-1)^2 = (0-1)^2 = (-1)^2 = 1$

• Fourth Question: y-intercept is negative

            $y = 5x^2-3x-5=5(0)^2-3(0)-5 = -5$

• Fifth Question: y-intercept is positive

            $y = (x+1)(x+2) = (0+1)(0+2) = 1 * 2 = 2$

Hope that helps!
