Let f(x) = x2 – 16 and g(x) = x + 4. Find fg f g and its domain.

Marta_Voda [28]

Answer: fg $=x^3+4x^2-16x-64$ and

Domain: All real number. All real number or $(-\infty,\infty)$

Explanation:

fg means product of two given function f(x) and g(x)

where,

$f(x)=x^2-16$ and $g(x)=x+4$

Now, we have to find fg

So, fg= $f(x)\times g(x)$

Substitute f(x) and f(x)

$\Rightarrow (x^2-16)(x+4)$

Using distributive property simplify above expression and we get,

$\Rightarrow x^3+4x^2-16x-64$

We can see it is cubic polynomial. So, domain of cubic polynomial is all real number.

Domain: All real number or $(-\infty,\infty)$

Kareem cannot decide which of two washing machines to buy. The selling price of each is 660$. The first is marked down by 40%.

natka813 [3]

Answer:

See explanation

Step-by-step explanation:

The selling price is $495.

The first washing machine:

- is marked down by 30%

$495 - 100%

$x - 100% - 30% = 70%

Find the value of x:

The second washing machine:

- is marked down by 20% with an additional 10% off

$495 - 100%

$y - 100% - 20% = 80%

Find y:

$y=$495 . 0.8 = $396$

Now,

$396 - 100%

$z - 100% - 10% = 90%

Find z:

$z=$396.0.9 = $356.40 = $356$

Thus, the sale price of the first washing machine is $347 and the sale price of the second washing machine is $356. The second machine is more expensive.

After a dilation with a center of (0, 0), a point was mapped as (4, –6) → (12, y). A student determined y to be –2. Evaluate the

crimeas [40]

That would not be right because 4 times 3 equals 12 and -6 times 3 equals -18.
