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

$3x ^ 2 + 6$

4. 1 less than twice the square of a number

givi [52]

Answer:

2(x^2)-1

Step-by-step explanation:

The square of a number is just the number squared. We don't know what the number is so I will just say it is x. So we have 2 times x^2. Then we have to minus 1 from that. So 2(x^2)-1.

Hope this helps! :D
