Three rectangular prisms have a combined volume of 518 cubic feet. Prism A has one third of the volume of Prism

timurjin [86]

A + B + C = 518 ft^3
A = 1/3B, or 3A = B
B = C
A + B + C = 518 ft^3
1/3B + B + B = 518
7/3B = 518
B = 518×3/7 = 222 ft^3
A = 1/3B = 1/3×222 = 74 ft^3
C = B = 222 ft^3

Which function does this graph correspond to?

tiny-mole [99]

ANSWER

The function that the given graph corresponds to is
$f(x) = (x - 2)(x - 1)(x + 1)(x + 2)$

EXPLANATION

The given graph in the attachment has x-intercepts at

$x = - 2 ,x=-1,x=1 \: \: and \: \: x=2$

These are the solutions of the polynomial function represented by the given graph.

We can write all these solutions as factors to obtain,

$x + 2 ,x + 1 ,x - 1 \: \:and \: \: x - 2$

The product of all these factors gives us the function whose graph was drawn.

This implies that,

$f(x) = (x - 2)(x - 1)(x + 1)(x + 2)$

Therefore the correct answer is option C.
