Question

Brandon found that a solution of x = 1 was extraneous for his function. What would be a possible denominator in Brandon's function?

2x + 4

x2 + 3x + 9

3x - 11

x2 + 3x - 4

Answer 1

x=1 must be a root of the denominator. since the denominator cannot be zero, it is undefined at this point.
seems like x2+3x-4=1+3-4=0 is the equation that youre looking for

Answer 2

thank you :)

Answer 3

no prob
