Answer:
The answer is C. Hope it helps :)
It's when we break a number apart. Like as if we take 3,864. And we take each number and put it in a area of the number.
3=Thousands.
8=Hundreds.
6=Tens.
4=Ones.
Fairly simple and easy.
Explanation
We must the tangent line at x = 3 of the function:

The tangent line is given by:

Where:
• m is the slope of the tangent line of f(x) at x = h,
,
• k = f(h) is the value of the function at x = h.
In this case, we have h = 3.
1) First, we compute the derivative of f(x):

2) By evaluating the result of f'(x) at x = h = 3, we get:

3) The value of k is:

4) Replacing the values of m, h and k in the general equation of the tangent line, we get:

Plotting the function f(x) and the tangent line we verify that our result is correct:
Answer
The equation of the tangent line to f(x) and x = 3 is:
Equation Form:
w x 2
19
Divide both sides by 2:
w
9.5
So, w must be equal to or greater than 9.5 for this equation to work.
A kid has $1 and he receives $1 everyday after doing his homework. So the initial money that he has is the y-intercept and the money that he receives everyday is the slope.
