sketch the graph and plot at least 5 points f(x) = -x^2 + 4x - 3
do you have a graphing calculator?
no :/
i have a graphing calculator:)
*shocked* well what we can do is plot 5 points f(-2) = -(-2)^2 +4(-1) -3 f(-1) = -(-1)^2 +4(-1) -3 f(0) = -(0)^2 +4(0) -3 f(1) = -(1)^2 +4(1) -3 f(2) = -(2)^2 +4(2) -3
nicceeee
awesome @Candlelover
@mollykenney does that help a bit mate?
i'm just confused with the plotting like i can draw the parabola but what are they looking for with the 5 points like… -3,0… 1,0… 3,0…2,1??
what kind of math are u guys doing?
this is algebra
yes it does @immanuelv thank you so much

@mollykenney glad that helped :D
ohh
so is that what there looking for with the 5 points? like (-3,0) (1,0) ?
yeah
ur very smart uv earned 89 meadls in math dang, oh well
ugh i feel so stupid that i'm confused… do you pick you own 5 numbers and plug them in when you first start the equation ? example how you chose -2,-1, etc
you got it @mollykenney you pick 5 numbers (since it wasn't given) and then you plug in to x to find f(x) aka y
wow thank you so much @immanuelv i really appreciate it
@mollykenney your're welcome :D
