NEED HELP EDU!! WILL GIVE BRAINLEIST! which graph of the cube root function f(x)=^3 √x?

Luden [163]

Answer:

C. $f(x)=\sqrt[3]{-x} -1$

Step-by-step explanation:

Consider graph of the parent function (red curve in attached diagram)

$g(x)=\sqrt[3]{x}$

First, multiply it by -1 to get function

$h(x)=-\sqrt[3]{x}$

Then translate the graph of the function h(x) 1 unit down, then you'll get the function

$f(x)=-\sqrt[3]{x} -1\\ \\ \text{or}\\ \\f(x)=\sqrt[3]{-x} -1$

The graph of the function f(x) is represented by the blue curve in attached diagram

What is twice 2 to the 30 power ? Write using exponents. Explain your reasoning

Rus_ich [418]

2 times 2^30 simple means that = (2^1) x (2^30)

In multiplying numbers of the same base (in this case 2), the exponents are just added, therefore giving us:

(2^1) x (2^30) = (2^31)

Answer:

2 to the 31 power
