Mathematics

kolezko [41]3 years ago

Answer:

To make it clearer, I just put every thing under the formal form

f(x) = \left \{ {{2x^2-1~~~~if~~~~  x\leq -1} \atop {3x+2~~~~~if~~~~~x>-1}} \right.

Step-by-step explanation:

Now, you have 2 equations with 2 conditions. One is > -1, and one is < -1.

The question is about f (5). So, which equation you use to replace x = 5? The first one or the second one? and why?

Answering those questions help you understand how it works.
