Y=-2|x+2|-4 i need to find y intercept and the x intercept
NeTakaya

Answer:

x-int: ∅

y-int: (0,-8)

Step-by-step explanation:

To find the x and y-intercept, simply plug in zero for x and y:

0=-2|x+2|-4\\4=-2|x+2|\\-2=|x+2|\\

Because an absolute value cannot be equal to a negative, there is no x-intercept.

y=-2|0+2|-4\\y=-2|2|-4\\y=-4-4\\y=-8

Hope it helps :)
