Intercepts of x2−4x−y+9=0x^{2} - 4 x - y + 9 = 0

The calculator will find the the x- and y-intercepts of x2−4x−y+9=0x^{2} - 4 x - y + 9 = 0, with steps shown.
Like x+2y=3, y=2x+5 or x^2+3x+4.

Your Input

Find find the x- and y-intercepts of x2−4x−y+9=0x^{2} - 4 x - y + 9 = 0.

Solution

To find the x-intercepts, substitute y=0y = 0 into the equation and solve the resulting equation x2−4x+9=0x^{2} - 4 x + 9 = 0 for xx (use the equation solver).

To find the y-intercepts, substitute x=0x = 0 into the equation and solve the resulting equation 9−y=09 - y = 0 for yy (use the equation solver).

Answer

No x-intercepts.

y-intercept: (0,9)\left(0, 9\right).
