I tried getting it into intercept form but it won't work, same with vertex. >.<

I'm guessing you were given a list of points?

always post the full question, instructions and answer choices

you don't always have to post the answer choices unless they are critical like in this case

jim_thompson5910 · Answer

let's test (0,3)

jim_thompson5910 · Answer

y = -x^2 + 5x - 3

3 = -(0)^2 + 5(0) - 3 ... plug in (x,y) = (0,3)

3 = -3 ... this is FALSE


so because we get a false equation, this means (0,3) does NOT lie on y = -x^2 + 5x - 3

I'll let you check the others

(2,3) ?
It's the only one I plugged in and got 3 = 3
