Question

What is the y intercept of the function f(x) =4-9x

Answer 1

GIVEN

The function is given to be:

`f(x)=4-9x`

SOLUTION

The y-intercept of a function is the value of the function when x = 0.

Substitute for x = 0 into the function;

`\begin{gathered} f(0)=4-9(0) \\ f(0)=4 \end{gathered}`

In coordinate form, the y-intercept of the function is (0, 4).

The LAST OPTION is correct.
