Average rate of change of function f(x) = x^2 +2 over the interval x= -5 to x= -2 is -7
Step-by-step explanation:
We need to find the average rate if change in the function f(x) = x^2 +2 over the interval x= -5 to x= -2
The formula used to find the change of average rate is:
Where b= -2 and a= -5
Finding f(b) and f(a)
f(b)=f(-2)=(-2)^2+2=4+2=6
f(a)=f(-5)=(-5)^2+2=25+2=27
Putting values in the formula:
Average rate of change of function f(x) = x^2 +2 over the interval x= -5 to x= -2 is -7

Answer:
All are rational.
Step-by-step explanation:
1)
=1/3/3/5
=1/3×5/3
=5/9
5/9 is non-terminating and recurring number so it is rational.
2)
4/3√9/5
=4/3*3/5
=4/5
4/5 is a terminating number it is rational.
3)
2*√16/√4
=2*4/2
=4
4 is a natural/whole number it is also rational.
