This is the series of (1/4)^n. The sum of these terms from n=0 to n=4 is 341/256
An easy way to solve this equation is to plug in the coordinates.
A. 6(2) + 8 ≠ 1
✅ B. 6(-1) + 8 = 2
C. 6(2) + 8 ≠ 4
D. 6(-2) + 8 ≠ 4
For most of them it literally says it above
Say for tons to ounces, you times 1 ton by 2000 for pounds, then times 2000 by 16 for ounces
Suppose that some value, c, is a point of a local minimum point.
The theorem states that if a function f is differentiable at a point c of local extremum, then f'(c) = 0.
This implies that the function f is continuous over the given interval. So there must be some value h such that f(c + h) - f(c) >= 0, where h is some infinitesimally small quantity.
As h approaches 0 from the negative side, then:
![\frac{f(c + h) - f(c)}{h} \leq 0 \text{, where h is approaching 0 from the negative side}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%28c%20%2B%20h%29%20-%20f%28c%29%7D%7Bh%7D%20%5Cleq%200%20%5Ctext%7B%2C%20where%20h%20is%20approaching%200%20from%20the%20negative%20side%7D)
As h approaches 0 from the positive side, then:
![\frac{f(c + h) - f(c)}{h} \geq 0](https://tex.z-dn.net/?f=%5Cfrac%7Bf%28c%20%2B%20h%29%20-%20f%28c%29%7D%7Bh%7D%20%5Cgeq%200)
Thus, f'(c) = 0
