A ball is thrown in the air from a ledge. Its height in feet is represented by f(x) = –16(x2 – 5x – 6), where x is the number of

Oduvanchick [21]

The ball takes 6 seconds to reach the ground.

Explanation

Height of the ball after $x$ seconds is represented by....

$f(x)= -16(x^2 -5x-6)$

The height of the ball is 0 feet when it hits the ground. So, for finding the number of second the ball takes to reach the ground, we will just plug $f(x)=0$ into the above equation and then solve for $x$ .

Thus...

$0=-16(x^2-5x-6)\\ \\ x^2-5x-6=0\\ \\ (x-6)(x+1)=0$

Using zero-product property....

$x-6=0\\ x=6$

and

$x+1=0\\ x=-1$ (Negative value is ignored as time can't be negative)

So, the ball takes 6 seconds to reach the ground.

Graph g(x), where f(x)=2x-5 and g(x)=f(x+1)

tigry1 [53]

Answer:

Graph g(x) = 2x - 3

Step-by-step explanation:

Plug in (x+1) to f(x) = 2x - 5:

g(x) = 2(x+1) - 5 = 2x + 2 - 5

g(x) = 2x - 3
