Question

Consider the function.
f(x) = 2*x+12
What is the y-intercept of f(x)?

Answer 1

The function is linear function of a form,

`f(x)=ax+b`

Which always intersects point,

`P(x, n)`

Or in this case,

`f(x)=2x+12`

The point is therefore,

`P(x,y)\Longrightarrow\boxed{P(x, 12)}`

The y-intercept is 12.

Hope this helps.

Answer 2

the question is already in slope intercept form.

The y-intercept is 12.

y=mx+b whereas m=slope, and b=y-intercept.
