Question

Given the function r(t)=t^2, solve for r(t)=4

Answer 1

Answer: t=2

Explanation:

Because we know that for some value of t, r(t)= 4, and for ALL values of t, r(t)= t^2, then we know for some value of t, that t^2 = 4.

Based off of this information, we can take the square root of both sides, resulting in this equation.

t =
`√(4)`

This can be simplified.

t=2

Answer 2

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

r(t)=t^2

r(t)=4​

t = ?

Step 02:

r(t)=4​

t ² = 4

t = √4

t = 2

The answer is:

t = 2
