2) Second function: f(x) A function, f, has an x-intercept at (2,0)→x=2, f(2)=0 and a y-intercept at (0,-10)→x=0, f(0)=-10 r=[f(2)-f(0)]/2 r=[0-(-10)]/2 r=(0+10)/2 r=(10)/2 r=5
3) Third function: g(x) r=[g(2)-g(0)]/2 From the graph: g(2)=6 g(0)=2 r=(6-2)/2 r=(4)/2 r=2
4) Fourth function: j(x) r=[j(2)-j(0)]/2 From the table: x=2→j(2)=-8 x=0→j(0)=4 r=(-8-4)/2 r=(-12)/2 r=-6
If Tim has a wire that is L inches long and each piece is k inches long, then you would divide the total length by the length of each individual to get the number of pieces.
