Answer:

(f-g)(x) = -x² +4x +6

Step-by-step explanation:

We assume you want to find (f -g)(x).

$(f-g)(x)=f(x)-g(x)=(4x+1)-(x^2-5)\\\\\boxed{(f-g)(x)=-x^2+4x+6}$

DedPeter [7]

Answer:

t = -14

Step-by-step explanation:×

I did 4+3 which equals 7.

Now I know I need t/-2 to equal 7.

Next, I did 7×2 which equals 14.

When you divide 2 negative numbers you get a positive number.

So -14 ÷ -2 = 7

So t = -14

PLEASE HELP! Given the function f(x) = 3x2 − 4, what is f(-2)?

EleoNora [17]

Answer: Variant C

Step-by-step explanation:

f(x) = 3x^2 − 4

For finding f(-2) just replace x with - 2 like this:

f(-2)=3*((-2))^2-4=3*4-4=12-4=8
