I need to know what the x and y intercepts are for these problems. if you could show work i would appreciate it. 1. f(x)=4x−8

2. f(x)=1/2x+2

3. f(x)=x^2-16

1.

  x = (2,0)

  y = (0,-8)

2.

   x  = (-2,0)

   y  = ( 0, 2)

3.

    x =  ( 4,0)

    y = ( 0, -16)

Step-by-step explanation:

aIll do one equation as an example

f(x) = 4x -8

y = 4x - 8

since its an intercept you know the x, for the y intercept will be zero and vice versa. Its like this cause its on the axis.

So you only need to figure out the y for the y intercept and the x for the x intercept.

- 4x  + y = -8

after changing the equation to standar form you then ignore the x base so, 4x to get the y intercept.

- 4x + y = -8 becomes  y = - 8 then you add the 0 for the coordinate

y = -8 becomes (0,-8)

f(x) = 4x -8

y = 4x - 8

- 4x  + y = -8

 y = - 8

(0,-8)

f(x) = 4x -8

y = 4x - 8

- 4x  + y = -8

-4x = -8

x = 2

(2, 0)

sorry im not really good at explaining lol

can g et a brainliest for effort at least 5 points isnt much
