# Writing a Transformation In Exercises 75–78, consider the vector-valued function r ( t ) = t 2 i + ( t − 3 ) j + t k . Write a vector-valued function s(t) that is the specified transformation of r.A vertical translation four units downward

To determine

To calculate: The vector valued function, s(t) that is a vertical transformation of r(t)=t2i+(t3)j+tk, four units downward.

Explanation

Given:

The vector valued function is: r(t)=t2i+(t3)j+tk. The vertical transformation four units downward.

Calculation:

Consider the provider vector value function,

r(t)=t2i+(t3)j+tk.

Compare the above equation with the standard equation r(t)=f(t)i+g(t)j+tk. Here, f(t)=t2,g(t)=(t3) and h(t)=t.

When vertical transformation k unit upwards of any vector then, the vector moves k units along the z-axis if z-axis along the vertical plane
