Solutions

Chapter 2.5, Problem 90E

a.

To determine

What shifting and shrinking operations must be operated on the function y=t2 to obtain the function y=C(t)

Expert Solution

Answer to Problem 90E

To shift y upward 2 units, shrink vertically by a factor of 12

Explanation of Solution

Given information : The question is

The temperature on a certain afternoon is modeled by the function C(t)=12t2+2

Calculation : The shift y upward 2 units, shrink vertically by a factor of 12

b.

To determine

To transform the new function y=C(t)

Expert Solution

Answer to Problem 90E

The shift of y upwards 32 units and y stretches vertically by a factor of 95

Explanation of Solution

Given information : The question is

The relationship between the Celsius and Fahrenheit degrees is given by F=95C+32

Calculation : first combine both C(t)=12t2+2 and F=95C+32

So, it starts out placing C(t) where ‘C’ is the second function

  y=95(12t2+2)+32y=910t2+185+32y=910t2+1785
