) We approximate the area under the graph of y = f(x), above the x-axis, over the interval [0, 4] by using n rectangles and left-hand endpoints. (Leave n as a parameter.) a) What is the width, Ax, of each rectangle used in this approximation? Ax b) Find a formula for the gridpoint x. (The only variables appearing in your expression should be k and n.) c) Nrite the Riemann sum for this area approximation in Sigma notation.
Percentage

Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
