Question

for which values of x is the function y-3/(2x+4)(x-5)

Answer 1

Any ideas?

Answer 2

you need to find out when you would divide by \(0\)

i.e. solve the following equations

\(2x+4=0\) and \(x-5=0\)

Answer 3

then exclude those

Answer 4

-2

Answer 5

and 5

Answer 6

-2 and 5

Answer 7

-2,5

Answer 8

so we would write that \(\{x|x\ne -2, x\ne 5\}\)

Answer 9

Do you why? @markkboyy

Answer 10

Why is the function not defined at those values of x?
