Step-by-step explanation:
A left Riemann sum approximates a definite integral as:
Given ∫₂⁸ cos(x²) dx:
a = 2, b = 8, and f(x) = cos(x²)
Therefore, Δx = 6/n and x = 2 + (6/n) (k − 1).
Plugging into the sum:
∑₁ⁿ cos((2 + (6/n) (k − 1))²) (6/n)
Therefore, the answer is C. Notice that answer D would be a right Riemann sum rather than a left (uses k instead of k−1).
Answer: Infinite solutions.
x could be equal to anything, and you can't solve for x since there is no equation on the other side of an equal sign for you to solve it. Hope that helps.

The answer to the equation is Y=3f
Hey there!
It’s a reflection because the two are going opposite ways. This is similar to the reflection you see in the mirror, your shirt probably looks backward and so does something you might be holding. It will go the opposite way, and that’s why when you look in the mirror it’s called a reflection- the flags are opposite so it’s a reflection.
Hope this helps!
