16 Investigation Question Step 1 Go to httgs:i'Mww.desmos.comfcalculator. Teach yourself how to use it. e.g. Type some equations e.g. y = 3x 4- Step 2 Go to httgjmrwwhom.ggv.aufclimatefaveragsftablesfcw USSUBZshtmI . Copy Sydney's maximum monthly Temperatures. In a spreadsheet (eg. Excel }, paste the temperatures. They will be in a row (since the data you copied was in a row}. Then EITHER Select and copy the {temperature} cells, then left click on a Dell anywhere leg. two or three oells below the cells with temperatures}. Right click and choose [in paste options} the fourth one. '2 Paste Options: The temperatures will now be in a column. 0R Manually type the monthly temperate in a column as shown below. Now Write D to 12 in the column next to the temperatures. 0 is January, 1 is February and so on. 12 is also January. 12 26 |include another January EITHER Select these twenty six cells and copy them (e.g. Ctri c) and then paste (Ctri v) into desmos. OR Copy the points into desmos (0,26), (1,25.8) , etc. to (12,26) . It's slow doing it this way and typing errors are likely. Step 3 Now find a function that fits the temperature data reasonably well. Take at least three screen shots (and save in a Word document) showing how you refined your function to fit the data. Write some comments about your function and how well it fits (and doesn't fit) the data etc. [Alternatively, you could do the above using Excel or other spreadsheet or graphing program. You will need to know how to enter equations in cells and create charts.]
