function f is a linear function with an initial value of 17 and a rate of change of -3 . Some values for the linear function f are shown in the table below . By how much does f exceed when x=5

Ican't do any of the other stuff, but i can get you started. the answer, i believe, is $2.50.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
