Question 23046: I am given a problem and I must use a t-chart and pick any number for x, and solving it for y. Then I must graph it. I am given the problem y=3xsquared. I have chosen to use the numbers (-2,-1,0,1,2) for X. Can you help me solve for y and graph it. I am unsure if you multiply 3 time x and then square it, or square x and then multiply that times 3

By order of operations agreement, you always raise to the power before you multiply!! So square the values of x, then multiply by 3, and that will give you the y values:

x=-2, y = 3*(-2)^2 = 3*4 = 12
x=-1, y = 3*(-1)^2 = 3*1 = 3
x= 0, y = 3*(0)^2 = 3*0 = 0
x= 1, y = 3*(1)^2 = 3*1 = 3
x= 2, y = 3*( 2)^2 = 3*4 = 12

If you graph these points it should look like this:
