Answer:

Although strictly speaking of mathematics i.e. theoritically,  

t

can take any value from  

{ − ∞ , ∞ ] ,

however, it is essentially a physical problem related to Physics and we cannot have negative  

t  i.e.  t ≥ 0

Further, after the maximum is reached at  t = 2  (observe that first differential is  h ' ( t ) = − 32 t + 64 , which is zero at  t = 2  and second derivative  h ' ' ( t ) = − 32  is negative and at this we have  h ( 2 ) = 64 ), at  t = 4 ,  h ( 4 ) = 0  i.e. toy rocket falls back to the ground and as such, we cannot have  h > 4 .

Hence, domain for  t  is  [ 0 , 4 ] .

Graph the function. Give domain and range in interval form.
sertanlavr [38]

Answer:

Domain: all real values of x

Range: all real values of y

Translation depends on the parent function

If the first function was:

y = cuberoot(x)

Then translation is:

Vertical translation 1 unit downwards
