Can someone help me find the y and x intercept, or tell me how to do it please.

f(x)=x^2-5x+4

Set x = 0 and solve for the y intercepts. "y" and f(x) mean the same thing.

Then set f(x)= y = 0 and solve for the x intercepts. There is only one y-intercept, at f(x) = y = +4.
Thank you.
Please tell me if this is correct.

x=4
y=-5
That is neither the x-intercept nor the y-intercept.

I already told you that the y intercept is at x=0, y=4.

The x intercepts are at x = (4,0) and at (1,0)
y=3x+3 and y=-2x+3
Please use "Post a New Question" for new questions.

If you are trying to solve two simultaneous equations in two unknowns, subtract the second equation from the first, in this case.

That will leave you with 5x = 0, so x = 0. Use either of the original equations for y.
