Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. What is the output of the function f(x) = x + 21 if the input is 4? When the input is 4, the output of f(x) = x + 21 is .

When the input is 4, the output of f(x) = x + 21 is 25.

Step-by-step explanation:

The given function is  

Here, x is input and f(x) is output.

We need to find the output of the given function f(x) if the input is 4.

Substitute x=4 in the given function.

So, the output value is 25.

When the input is 4, the output of f(x) = x + 21 is 25.

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
