what is the y-intercept of the following function? How do you know?
f(x) = x^2 + 4x + 6

Answer 1

6

Explanation:

the y-intercept is the last number of the equation

so because 6 is the last number, the y-intercept is 6

Answer 2

The y-intercept is 6

Explanation:

The y-intercept of a function is where the graph of an equation touches or crosses the vertical axis. This is usually the value of y when x = 0.

For this particular function, when x = 0 ⇒

f(0) = 0^2 + 4(0) + 6

= 0 + 0 + 6

= 6

Therefore, the y-intercept of this function is 6
