J 6.222 and 6.238 rounds to 6.22, 6.24

_____

One way to determine the rounded value is to add 0.005 to the number, then drop all digits to the right of the hundredths place.

Examples:

6.222 +0.005 = 6.227 ⇒ 6.22

6.238 +0.005 = 6.243 ⇒ 6.24

If f(x)=4x2=1 and g(x)=x2-5, find (f-g)(x) A:3x2+6 B:5x2-6 C:3x2-4 D:5x2-4

Alex787 [66]

For this case we have the following functions:

$f (x) = 4x ^ 2 + 1\\g (x) = x ^ 2-5$

We must find $(f-g) (x):$

By definition of operations with functions we have:

$(f-g) (x) = f (x) -g (x)$

So:

$(f-g) (x) = f (x) -g (x) = 4x ^ 2 + 1- (x ^ 2-5) = 4x ^ 2 + 1-x ^ 2 + 5 = 3x ^ 2 + 6$

Answer:

Option A

$3x ^ 2 + 6$
