Answer: 4 (choice E)

Explanation:

Comparing the two equations your teacher mentioned, we see that a = 2. This directly and solely determines the amplitude. The amplitude is |a| = |2| = 2. This is half of the vertical distance from min to max. So that full vertical distance is 2|a| = 2*2 = 4

a road follows the shape of a parabola f(x)=3x2– 24x + 39. A road that follows the function g(x) = 3x – 15 must cross the stream

Nonamiya [84]

the coordinates where the bridges must be built is $(3,-6)$ and $(6,3)$ .

<u>Step-by-step explanation:</u>

Here we have , a road follows the shape of a parabola f(x)=3x2– 24x + 39. A road that follows the function g(x) = 3x – 15 must cross the stream at point A and then again at point B. Bridges must be built at those points.We need to find Identify the coordinates where the bridges must be built. Let's find out:

Basically we need to find values of x for which f(x) = g(x) :

⇒ $f(x)-g(x)=0$
