What is the y-intercept of the function f(x) = -3x
ο
ο
on who wire on
ο
ο

see the explanation

Step-by-step explanation:

we know that

The y-intercept is the value of the function when the value of x is equal to zero. Also is called the initial value of the function

I will analyze two cases

Part 1) we have

so

For x=0

substitute

therefore

The y-intercept is the point (0,0)

Part 2) we have

so

For x=0

substitute

therefore

The y-intercept is the point (0,-1)

the correct answer is seven more than a number. the unknown number is y and you are adding 7 to it.
