Introduction to Excel.
Tables in a spreadsheet
A: x is 5
to -5 in 10 steps ( size of 1)
B: y is = 3*x + 1
C: y =
-2x^{2}
- 8x +3 = -2*x^2 - 8*x + 3

Use a speadsheet to find the
largest value of y in each of the following:
- y = -5x^{2}
- 10x + 4 with x between
-5 and 5.
- y = -x^{2} +
4x + 4 with x
between -5 and 5.

- Use winplot to look
for the largest value of y in each of the following:
- y = -5x^{2}
- 3x + 4 with x between
-5 and 5.
- y = -5x^{2}
- 6x + 4 with x between -5 and 5.
