How do I plot the points .....?

Question

y = x^2 -5x + 3


and these points as well


y = -x^2 +6x -2


Thanks

Answer 1

Have you heard of a T-chart.
Assign arbitrary numbers for x (-3,-2,-1,0,1,2,3) and plug them into the equation to solve for y.
Plot your x and corresponding y on a graph and draw a line through them.

Answer 3

find y by substituting various values of x into the right hand expression:
x = 1 y = -1
x = 2 y = -3
x = 2.5 y= -3.25
x = 3 y = -3
x = 4 y = -1

when the above points are plotted the result will be a parabola oening upward with vertex at 2.5,-3.25

The second problem is solved in the same manner.

Answer 4

Use a graphing calculator
