For f(x) = 3x +1 and g(x) = x2 – 6, find (f – g)(x). a. x2 – 3x – 7 b. –x2 + 3x + 7 c. –x2 + 3x – 5 d. 3x2 – 17

 Option (b) is correct.

Step-by-step explanation:

Given : Functions and

We have to choose the correct option from the given options that represents (f-g)(x)

Consider the given functions

and

then , (f - g)(x) = f(x) - g(x)

Substitute, we have,

Applying plus - minus rule, we have,

Simplify and write in standard form, we have,

Thus, The

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.
