Question

with the given domain, find the ranges

a) f(x)=3-2x for -2<x<2 (the < have a _ below it)

b) f(x)=x^2 for -5<x<-2

what does the for means. ive been stuck with this two questions for hours any solutions would be appreciated TT

Answer 1

The range of a function is the complete set of all possible resulting values of the dependent variable.

a)

$f(-2)=3+4=7$

$f(2)=3-4=-1$

Range: $y\isin(-1,7)$

b)

$f(-5)=25$

$f(-2)=4$

Range: $y\isin(4,25)$
