Question

for my practice review I am supposed to find the domain and range of g using interval notation and I am confused on how to do that.

Answer 1

step 1

Find the domain

the domain are the values of x

so

the domain is the interval (-1,4)

-1 < x < 4

all real numbers greater than -1 and less than 4

step 2

Find the range

The range are the possible values of y

in this problem

the range is the interval (-4,5}

all real numbers greater than -4 and less than or equal to 5

`-4\text{ < y }\leq5`
