Answer:

-3

Step-by-step explanation:

Given, f(x)=-4log2(x+3)-6

So, for domain of f(x) ,we have to find the domain of log2(x+3) as all other things are just numbers which do not affect the domain.

For domain of f(x), 2(x+3) > 0

Thus, x + 3 > 0

x > -3.

So, all real numbers greater than -3 are in the domain of f(x).

Which statements are true about the polynomial function? f(x)=x4+5x3−x2−5x

topjm [15]

Answer:

f(5) is NOT 0.

When x=-5, f(x) IS 0.

f(x) divided by (x+5) has a remainder of 0. (x+5) is a factor of f(x).

But x-5 is NOT a factor of x.

Answer:

1. if x + 5 = 12, then x = 7

:Subtraction property of equality

2. If x + y = 20, and y = 5, then x + 5 = 20.

:Substitution property of equality

3. If 2x3 = 11, then 11 = 2x - 3.

:Symmetric property of equality
