CLEP COLLEGE ALGEBRA (ACTUAL / ) QUESTIONS

AND VERIFIED CORRECT ANSWERS WITH SOLUTIONS

find the additive inverse of (expression) ----Answers----solve

the equation for y: y + (expression) = 0

it is the negative of the expression

raise expression to a negative number ----Answers----1/ (expression)^n

raise to a fractional power ----Answers----expression^1/n = n rt (expression)

to determine whether a graph is a function ----Answers---- vertical line test

determine whether a graph matches that of an algebraic function ----Answers----plug x-values into the function to find the value of y, and determine if those points are on the graph

given y=f(x) find the domain ----Answers----domain will be infinity, infinity with 3 exceptions

• any value of x that makes the denominator 0
• any value of x that makes an even root of a negative number 1 / 2

• any value of x that makes a term into the log of zero or the

log of a negative number

graph a line y=mx+b ----Answers----chose two values for x and find the values of y draw a line between both points

determine whether a graph is odd, even, or neither ---- Answers----even- if the graph is symmetrical with respect to y-axis odd- if the graph is symmetrical with respect to the origin (I and III and II and IV are mirror images)

given f(x) describe transformations ----Answers----f(x) + a is a units up f(x) - a is a units down f(x-a) is a units to the right f(x+a) is a units to the left -f(x) reflects across x-axis

given a graph, determine how many roots ----Answers---- how many times the graph touches/crosses the x-axis

given a polynomial of degree n find the max and min # of roots ----Answers----max number of real roots is n if n is even, the min is 0 if n is odd the min is 1
