<h2>Answer:</h2>

<u>our parabola open </u><u>downward</u><u> and therefore a is negative</u>

<h2> Explanation:</h2>

As value of a changes from positive to negative or from negative to positive, the direction of opening changes.  For  negative values of a we got negative parabolas that open downward.  As the original formula y = x^2 we see that x^2 will always be positive because when you square a number it always gives positive value. Therefore  the direction for which it will open, depends on  value of a.

What number will the function return if the input is 15.4?
wlad13 [49]

The rule of the function is to multiply the input by 3, since one yard is equal in length to three feet.

So, if the input is 15.4, the output will be

f(x)=3x \implies f(15.4)=3\cdot 15.4 = 46.2
