NEED HELP EDU!! WILL GIVE BRAINLEIST!<br> 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

A box has length 4 feet, width 8 feet, and height 7 inches. Find the volume of the box in cubic feet and in
Lubov Fominskaja [6]

Answer:

32 256 cubic inches

18.7 cubic feet

Step-by-step explanation:

4 feet = 4 × 12 = 48 inches

8 feet = 8 × 12 = 96 inches

7 inches = 7 ÷ 12 = 0.583 feet

Volume = length × width × height

V = 48 × 96 × 7 = 32 256 cubic inches

V = 4 × 8 × 0.583 = 18.7 cubic feet
