Use the graph of the function y = 4x to answer the following questions.

the domain of the function is ~~~
to ~~~
because an exponent can be any real number.

Hello from MrBillDoesMath!

For y = 4x, the domain of the function is all real numbers. This can be indicated  as ( -infinity, infinity),

...later part of question:...

..."because an exponent can be any real"

exponent?   !!!

Did you mean y = 4^x ? In this case the domain of y is all real numbers ann the range is (0, infinity), where the value 0 is not included in the range.

Thank you,

MrB

The domain of the function is negative infinity to positive infinity because an exponent can be any real number.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

so, converting firstly the mixed fractions to improper fractions and then "adding".
