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 = -2x2
- 8x +3 = -2*x^2 - 8*x + 3
Record your answers for the next work and submit them on Moodle by Wednesday, Sept.5.
Use a speadsheet to find the largest value of y in each of the following:
- y = -5x2
- 10x + 4 with x between -5 and 5.
- y = -x2 + 4x + 4 with x between -5 and 5.
