#3 find domain and range using interval notation

kkurt [141]

Hey there! :)

Answer:

D : [-4, ∞)

R: [-2, ∞)

Step-by-step explanation:

Notice that one end of the graphed function has a closed circle, and one end is a line. We must use specific brackets accordingly:

[ is used for closed points.

( is used for arrows or open circles.

Therefore:

This graph goes from x = -4 towards x ⇒∞. Therefore:

D : [-4, ∞)

The range of this function goes from x = -2 towards y⇒ ∞. Therefore:

R: [-2, ∞)

Given f(x)=2^x and g(x)=f(x-3)+4, write the new function rule (equation) for function g and describe (using words*) the two tran

miss Akunina [59]

Answer:

The first thing we do is find out what f(x-3) is
$f(x)=2^x\\f(x-3)=2^{x-3}$ this is can be simplified using the rules of exponents
$f(x-3)=2^{x-3}\\f(x-3)=2^x\div2^3\\f(x-3)=\frac{2^{x}}{8}$
Then we put that into g(x)
$g(x)=f(x-3)+4\\g(x)=\frac{2^{x}}{8}+4$
The first transformation is at f(x), where it is divided by 8, and then inserted into g(x) which increases the new transformed f(x) by 4

If (1)=0, what are all the roots of the function f(x)=x3+3x2-x-3?use the remainder theorem

Anon25 [30]

If $f(1)=0$ , then by the remainder theorem $\dfrac{f(x)}{x-1}$ has a remainder of 0, which means $f(x)$ is divisible by $x-1$ . In fact,

$x^3+3x^2-x-3=x^2(x+3)-(x+3)=(x^2-1)(x+3)=(x-1)(x+1)(x+3)$

So we know 1 is a root, and the other two roots are -1 and -3.

Why can you use fraction multiplication to check the answer to a fraction division problem? How do you use multiplication to che

erica [24]

Fraction division is basically multiplication of a reciprocal.

For example (1/4)/(1/8) = (1/4)x(8/1)=2

Multiplication of the answer and the piece that divides (in this case 2 x 1/8), you should get the piece that is being divided (in this case 1/4). If that is correct, then your division is correct.
