Answer 1

So to find the value of -3 do the following process:

Insert the -3 in the x’s in the equation on the top of the table

y= 5x -3x to the second power + 3

y= 5 (-3) -3(-3) to the second power + 3

Then continue to simplify the equation

y= -15 + 9 to the second power + 3

y= -15 + 84

y = 69

Y= 69 for the chart for -3

For b, c, and d insert the number in the x values and simplify like the previous equation.
