Question

What is the range of the function f(x) = –2|x + 1|

Answer 1

Answer:

$f\left(x\right)\le \:0$

Step-by-step explanation:

$\mathrm{The\:range\:of\:an\:absolute\:function\:of\:the\:form}\:-c|ax+b|+k\:\mathrm{is}\:\:f\left(x\right)\le \:k$

$f(x) = -2|x + 1|+0$

$k=0$

$f\left(x\right)\le \:0$
