Question

Please help me understand the following problem. Calc III: Intro to vector-valued functions. I am asked to describe the graph of the equation.
r=(3-2t)+5tj

Answer 1

I am not sure what steps are required to picture this function mentally...

Answer 2

A two-dimensional vector function is defined as follows
\[
\textbf{r}(t)=f(t)\mathbf{i}+g(t)\mathbf{j}.
\]What you gave us is not a vector function.

Answer 3

The title of the section is "introduction to vector-valued functions". I never claimed the equation was a vector-valued function.

Answer 4

Your function makes no sense.
