Just find the slope between the points
basically find (f(10)-f(7))/(10-7)
f(7)=7^2-3(7)-4=49-21-4=24
f(10)=10^2-3(10)-4=100-30-4=66
slope=(66-24)/(10-7)=42/3=14
average rate of change is 14
It is -11.34
-$68.04 divide by 6 is -$11.34, so instead of 11.34, it's -11.34
No because they 90 to 200 is 110 but 200 to 325 is 125
110 obviously does not equal 125
Answer:
Obviously only D is true
Note 2 x - 1 < 10 can be rewritten
2 X < 11 and
x < 5.5
So all of the values in the set would have to be less than 5.5
