Answer:

Step-by-step explanation:

Based on the information provided we can create the following direct proportion equation...

D = 3.5x

In this equation, the variable D represents the distance that Brianna has walked while the variable x represents the number of hours she walked. In this equation, the constant of proportionality would be the 3.5 miles that Brianna walks per mile. This value affects the entire equation because it is multiplied by the number of hours Brianna walks which is directly proportional to the Distance she travels, as one value increases so does the other.

WHAT IS A 2ND DEGREE POLYNOMIAL FUNCTION WHOSE GRAPH HAS ONLY POSITIVE Y-VALUES
elena55 [62]

An example of quadratic equation with this behavior is:

y = x^2 + x + 20

Which is sketched at the end of this answer.

A quadratic equation has the format:

y = ax^2 + bx + c

It's roots are given by:

\frac{-b \pm \sqrt{\Delta}}{2}

The number of roots depends on the discriminant \Delta = b^2 - 4ac, that is:

  • If \Delta > 0, it has two different real roots.
  • If \Delta = 0, it has one real root.
  • If \Delta < 0, it has no real roots.

In this problem, it will have only positive y-values if: \Delta < 0 and c > 0

Thus, an example is:

y = x^2 + x + 20

Which is sketched below.
