Question

Precal HELP please, Rational equations graphing
list all intercepts and all asymptotes using correct format
1) f(x) = 1/x
2) g(x) = 4x +3 3 / x+4

Answer 1

To find the y intercept, plug in x = 0 and evaluate

f(x) = 1/x

f(0) = 1/0 ... replace every x with 0

f(0) = undefined

it's undefined because we cannot divide by zero. So there are NO y intercepts

Answer 2

To find the x intercepts, you replace f(x) with 0 and solve for x


f(x) = 1/x

0 = 1/x ... replace f(x) with 0


what do you get when you solve for x?

Answer 3

0? and thank you so much!
