For f(x)=4x+1 and g(x)=x^2-5, find (f-g)(x).

C

Step-by-step explanation:

note (f - g)(x) = f(x) - g(x)

f(x) - g(x)

= 4x + 1 - (x² - 5) ← distribute by - 1

= 4x + 1 - x² + 5 ← collect like terms

= - x² + 4x + 6 ← in standard form → C

For this case we have the following functions:

We must find By definition we have to:

So:

We take into account that:

Option C

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
