Answer: 5^7 + 5^6 = 15625 x 6
Explanation:
5^7 = 78125
5^6 = 15625
Add both answer together to get 93750 and divide it by 6
= 15625
Question 1: (0,2) because b value in mx+b is y-intercept
Question 2: plug in 4 for x you will get 1 so max is (4, 1)
Question 3: plug in -4 for x you will get -5 so min is (-4, -5)
Hope it helps :D

Answer:
Approximation f(25.3)=5.03 (real value=5.0299)
The approximation can be written as f(x)=0.1x+2.5
Step-by-step explanation:
We have to approximate
with a linear function.
To approximate a function, we can use the Taylor series.

The point a should be a point where the value of f(a) is known or easy to calculate.
In this case, the appropiate value for a is a=25.
Then we calculate the Taylor series with a number of terms needed to make a linear estimation.

The value of f'(a) needs the first derivate:

Then

We evaluate for x=25.3

If we rearrange the approximation to be in the form mx+b we have:

Then, m=0.1 and b=2.5.
