CLEP EXAM – PRECALCULUS
QUESTIONS & ANSWERS9
natural numbers - ANSWERS-1, 2, 3, 4, and so on.
exponential growth model - ANSWERS-A(t)=A(o)e^rt
whole numbers - ANSWERS-0, 1, 2, 3, and so on.
integers - ANSWERS-0, ±1, ±2, ±3, and so on.
perfect squares - ANSWERS-1 4 9 16 25 36 49 64, and so on.
rational number - ANSWERS-A rational number is simply a number of arithmetic: Any whole
number, fraction, mixed number, or decimal; together with its negative image.
A rational number can always be written in what form? - ANSWERS-As a fraction, where a and b
are integers (b not equal to 0).
Which natural numbers have rational square roots? - ANSWERS-Only the square roots of the
square numbers; that is, the square roots of the perfect squares.
real number - ANSWERS-A real number is distinguished from an imaginary or complex number.
It is what we call any rational or irrational number.
They are the numbers we expect to find on the number line.
They are the numbers we need for measuring.
, function - ANSWERS-A rule that relates two variables, typically x and y
domain - ANSWERS-The values that x may assume
range - ANSWERS-the values of y that correspond to the values of x
value of the function - ANSWERS-value of y
independent variable - ANSWERS-x
dependent variable - ANSWERS-y
f(x) = x2 and g(x) = x + h.
f(g(x)) - ANSWERS-f(x + h) = (x + h)2 = x2 + 2xh + h2
f(x) = x2 and g(x) = x + h.
g(f(x)) - ANSWERS-g(x2) = x2 + h
