Answer 1

\[x ^{2} + 2x - 3\] draw chart to show at least three ordered pairs that are on the graph

Answer 2

Go on wolfram alpha to check the chart

Answer 3

Then plot the points, any points you want.

For the x value of 0:
f(0) = 0^2 + 2(0) -3 = -3


f(1) = 1^2 + 2(1) -3 = 0
f(2) = 4 + 8 - 3 = 9
f(3) = 9 + 6 - 3 = 12

Does this make sense?

Answer 4

Yeah. but how..what r the points. id graph

Answer 5

Okay. Well the first x value is 0, and I found out that the y value is -3
(0,-3)

When I put x = 1 into the equation, I got y = 0
(1,0)

Do you see the pattern. With any given x value, you can find the corresponding y value

Answer 6

ok
