myininaya (myininaya):

when is top 0?

OpenStudy (anonymous):

what?

OpenStudy (anonymous):

4-x=0

myininaya (myininaya):

a.k.a the numerator right lagrange has it

OpenStudy (anonymous):

x=4

OpenStudy (anonymous):

im confused. the problem said to find the zeros of the function and I put the function equal to 0. so is x=4 the only zero?

OpenStudy (anonymous):

thats right

OpenStudy (anonymous):

when x=4, is a zero of this function

OpenStudy (anonymous):

but what about the denominator?

OpenStudy (anonymous):

the denomiator has nothing to do with finding the zero of this function. If the denomiator is zero, this function is undefined at that value of x.

OpenStudy (anonymous):

wow duh its been awhile since ive done this lol
