2. Let f(x) = r² – 6r – 7 a) Find the critical numbers of the function. Show clearly and specifically which of the criteria is met to warramnt the classification as critical mumber. b) Find the absolute maximum and minimum values of the function on the interval [0, 5]. Give both simplified, exact values as well as approximations to the nearest tenth.
Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
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.
Addition
Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.
