Question

Which point lies on the graph of the function shown below?
y = -x^2 + 5x - 3

How would I solve this?

Answer 1

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

Answer 2

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

Answer 3

M'hmm.
Did yhu want me to post 'em?

Answer 4

yes please

Answer 5

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

Answer 6

let's test (0,3)

Answer 7

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

Answer 8

I'll let you check the others

Answer 9

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