What is the y-intercept of the function f(x) = -3x<br> Ο<br> Ο<br> on who wire on<br> Ο<br> Ο
morpeh [17]

Answer:

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

f(x)=-3x

so

For x=0

substitute

f(0)=-3(0)=0

therefore

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

Part 2) we have

f(x)=-3^x

so

For x=0

substitute

f(0)=-3^0=-1

therefore

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

tamaranim1 [39]

Answer:

the value to be written is -2

Step-by-step explanation:

The first thing we will do here is to set the divisor equals to zero

The divisor is the denominator

Thus, we have x + 2 = 0

This indicates that x = -2

The term to be written in front of the coefficients is -2
