x - intercept : None

Y- intercept: (0, -5)

Step-by-step explanation

X-intercept is the point on f(x) where the value of y=0.

Given the function f(x) = -2| x+1 | - 3

To find the x - intercept, put f(x) = 0 and solve for x.

0 = -2| x + 1 | - 3

Add 3 to both-side of the equation.

3 = -2 | x + 1 |

Divide both-side of the equation by -2.


(3)/(-2)=|x+1|

- 1.5 =| x + 1|

|x + 1 | = - 1.5

There is no value of x that satisfies the above equation.

Hence, there is no x - intercepts.

Y- intercept

It is a point on the function f(x) at which x = 0.

To find the y-intercept, substitute x = 0 into the equation given and simplify.

f(0) = -2|0+1| - 3

f(0) = -2|1| - 3

f(0) = - 2 - 3

f(0) = -5

Hence, the y-intercept is (0, -5)
