Find the range of the following function

OpenStudy (mathmath333):

\(\large \color{black}{\begin{align}f(x)=2-3x,\ x\in \mathbb{R},\ x>0 \hspace{.33em}\\~\\ \end{align}}\)

geerky42 (geerky42):

Can you graph 2-3x?

OpenStudy (mathmath333):

i cant use graph paper, i have to use pen and paper

OpenStudy (acxbox22):

you can still create a simple graph

geerky42 (geerky42):

then label y-intercept and x-intercept, so you can have good idea of what graph would look like.

You could also find the domain of the inverse with the given restrictions.

OpenStudy (mathmath333):

what to do next @geerky42 after graphing

OpenStudy (acxbox22):

well the line crosses the y axis at (0,4) and it asks for range when x is greater than 0 and range means all the y-values the graph goes through

geerky42 (geerky42):

Good, now what would graph look like with restriction of x>0? Once you figured that part, you should be able to tell what range is.
