Question

Which t shirt design has the lowest valley floor over the first 6 inches of the design

Answer 1

Given:

`m(x)=-1.4x^4+16.6x^3-68x^2+112.9x-50`

m(x) represents Mariana's design while the given graph represents Chloe's design.

Here, x is the horizontal distance from the left edge of the design.

Let's find the design which has the lowest valley floor over the first 6 inches.

From the graph, the lowest valley for Chloes's design c(x) is approximately 9.5 inches.

For Mariana's design, we have the graph below:

From the graph above, we can see that for m(x), there is no valley for the first 6 inches.

Therefore, we can say Marianna's design doesn't have a valley floor for the first 6 inches of the design.

• ANSWER:

Marianna's design doesn't have a valley floor for the first 6 inches of the design.
