Question
In Exercises 105-108, determine the $x$-and $y$-intercepts, if they exist, of the graph of each equation.$$x=y^{2}-6 y-7$$
Step 1
To do this, we set y = 0 and solve for x: x = (0)^2 - 6(0) - 7 x = -7 So the x-intercept is (-7, 0). Now, let's find the y-intercept. To do this, we set x = 0 and solve for y: 0 = y^2 - 6y - 7 This is a quadratic equation, so we can use the quadratic formula Show more…
