Question

find the zero of f(x)=3/4x-12

Answer 1

I think you missed an x somewhere.

Answer 2

ah you're right! f(x)=3/4x-12

Answer 3

The "zero" is when this graph crosses the x-axis and therefore has a 0 for y. f(x) =y and you want y to =0 so f(x)=y=0 or f(x)=0

So:
0=3/4x -12 Now solve for X.

Answer 4

16?

Answer 5

Yes. So the zero is where x = 16 and y = 0 or (16,0)

Answer 6

hoorah! thank you :D
