Question

Determine the x-values that make the function undefined.
a.) f(x) = 3 over 2 x - 5
b.) f(x) = 4x + 1 over x^2 + 5x + 4

Answer 1

for a solve the denominator for x, that is your undefined value

Answer 2

for b factor the denominator, if nothing cancels out then solve the denominator for x and that will be your undefined values as well
