Answer:

see below

Step-by-step explanation:

The first part of the function, f(x) = -2x (for x < -1), is only graphed correctly in the first and third graphs.

The second part of the function, f(x) = -1 (for -1 ≤ x < 2) is only graphed correctly in the first graph, which also correctly graphs the third part of the function,

The appropriate choice is the first graph.

What is the answer to this?

Answer:

x < 2.5
x > 2.5

Step-by-step explanation:

One way to do this is to try a number for x and see if it makes the inequality true. A suitable number here is x=0. This value of x is less than 2.5.

For x=0, you have ...

5 > -5 . . . . . true; the solution space is x < 2.5

For x=0, you have ...

-25 > -5(2.5)

-25 > -12.5 . . . . . false; the solution space is x > 2.5

_____

<em>Alternate solution</em>

Subtract 5:

-4x > -10

Divide by -4

x < 2.5

Divide by -5:

5 < x +2.5

Subtract 2.5

2.5 < x

x > 2.5
