Just find the slope
that is ((f(6)-f(2))/(6-2)
f(6)=6^2+5(6)-8=36+30-8=58
f(2)=2^2+5(2)-8=4+10-8=6
average is (f(6)-f(2))/(6-2)=(58-6)/(4)=52/4=13
average rate of change is 13
Answer:
21.42x+28.56
Step-by-step explanation:
Expand: 4.2×5.1×x+4.2×6.8
4.2×5.1×x to (21.42)x
Simplify: 21.42x+4.2×6.8
4.2×6.8 = 28.5628.56
21.42x+28.56
