Find (f - g)(x)

Sidana [21]

Answer:

Step-by-step explanation:

We have the two functions:

$f(x)=3x^2-2x\text{ and } g(x)=9x^2-x+7\\$

And we want to find:

$(f-g)(x)$

This is equivalent to:

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

Hence, by substitution:

$=(3x^2-2x)-(9x^2-x+7)$

Distribute:

$=(3x^2-2x)+(-9x^2+x-7)$

Rearrange:

$=(3x^2-9x^2)+(-2x+x)+(-7)$

Combine like terms:

$=-6x^2-x-7$

Hence, our answer is A.

Describe how (2^3)(2^-4) can be simplifed

yanalaym [24]

Answer:

$2^3\times2^{-4}=\frac{1}{2}$

Step-by-step explanation:

The given expression is

$(2^3)(2^{-4})$

This is the same as;

$2^3\times2^{-4}$

Recall that;

$a^m\times a^n=a^{m+n}$

This implies that;

$2^3\times2^{-4}=2^{3+-4}$

$2^3\times2^{-4}=2^{-1}$

We now use the following law of exponents

$a^{-m}=\frac{1}{a^m}$

This gives us;

$2^3\times2^{-4}=\frac{1}{2}$
