Domain and Range Number 2,3,4

1 answer:

7 0

The image is sorta blurry for me so I can't give you answers but <u>to find the domain and range you need to know that domain is x (here,y) while range is y (x,here).</u>

For example (2,9) - 2 is the domain and the range would be 9.

The Fahrenheit and Celsius scales are related by the equation F=9/5C+32. What temperature is equal to a body temperature of 98.6

____ [38]

$\textbf{Substitute\ in\ the\ equation}$

$\displaystyle 98.6 = \frac{9C}{5} +32$

$\textbf{Solve\ for\ }C$

$\displaystyle 66.6 = \frac{9C}{5}$

$333=9C$

$\large C=\textbf{37 \textdegree C}$

1) Suppose f(x) = x2 and g(x) = |x|. Then the composites (fog)(x) = |x|2 = x2 and (gof)(x) = |x2| = x2 are both differentiable a

Rufina [12.5K]

Answer:

This contradict of the chain rule.

Step-by-step explanation:

The given functions are

$f(x)=x^2$

$g(x)=|x|$

It is given that,

$(f\circ g)(x)=|x|^2=x^2$

$(g\circ f)(x)=|x^2|=x^2$

According to chin rule,

$(f\circ g)(c)=f(g(c))=f'(g(c)g'(c)$

It means, $(f\circ g)(c)$ is differentiable if f(g(c)) and g(c) is differentiable at x=c.

Here g(x) is not differentiable at x=0 but both compositions are differentiable, which is a contradiction of the chain rule
