-14 points SPreCalc6 2.6.001 From the graphs of f and g in the figure, we find the following. (Assume that each point lies on the gridlines.) (f+g)(8) = (fg)(8) = (8)-1

Solution

from the graph

f(8)=3, g(8)=4

(f+g)(8)=f(8)+g(8)=3+4=7

(f-g)(8)=f(8)-g(8)=3-4=-1

(fg)(8)=f(8)*g(8)=3*4=12

(f_/g)(8)=f(8)_/g(8)=3_/4=0.75

please rate if helpful. please comment if you have any doubt
