Question

Could you help me solve y = x^2+6x+7?

Answer 1

x ≈ -1.585786438 or x ≈ -4.414213562

y = 7

Explanation:

This should be a parabola function.

Let y = 0 so we can find the two x-intercepts. (x1,0) and (x2,0)

x^2+6x+7 = 0

Using the quadratic equation, we get:

x ≈ -1.585786438 or x ≈ -4.414213562

Now we can find y by setting x = 0, so that we get a y-intercept. (0,y)

y = 0^2+6(0)+7

y = 7
