WGU C957 Applied Algebra Brandy 2025 EXAM QUESTIONS
WITH ACCURATE VERIFIED ANSWERS (ACCURATE
SOLUTIONS) A+ PASSED!!
Asymptote - ANSWER✔✔-a horizontal, vertical, or slanted line that a graph approaches
but never touches
coefficient of determination - ANSWER✔✔-A statistic that measures how well a
regression prediction approximates the real data points. An r^2 of 1 indicates that the
regression prediction is a perfect fit for the data
common ratio - ANSWER✔✔-The number by which each term in a sequence is
multiplied to find the next number in the sequence; for example 4 is the common ratio
for the sequence [1, 4, 16, 64, 256...]
Constant ratio - ANSWER✔✔-Occurs when the numeric relationship between two
quantities- that is, how many times one number contains the second- remains
unchanged over time

, Data regression - ANSWER✔✔-The process of examining data points to determine a
valid equation. "Regression" refers to bringing different data points down toward a
normal average- "regressing" them
equation - ANSWER✔✔-A mathematical sentence that contains an equals sign.
explanatory variable - ANSWER✔✔-A variable that, as it changes, affects another
variable (called the response variable); for example, as a person pumps more gas into a
car's tank(the explanatory variable), the cost of the purchase rises (the response
variable)
exponent - ANSWER✔✔-A mathematical notation indicating the number of times a
quantity is multiplied by itself.
exponential function - ANSWER✔✔-a function of the form f(x) = ab^x, where a and b
are real numbers with a ≠ 0, b>0, and b ≠ 1
extrapolation - ANSWER✔✔-the act of estimation by projecting known information
f(x)=mx+b - ANSWER✔✔-linear function
f(x) = mx - ANSWER✔✔-A very basic function
function - ANSWER✔✔-A relation based on a set of inputs and a set of possible outputs
where each input is related to exactly one output
