HELP PLEASE!! Which of the following best describes the graph below? A. it us a one-to-one function B. it us a function but it i

masha68 [24]

The correct statement regarding the function $y = \sqrt{x + 2}$ is given by:

A. it us a one-to-one function.

<h3>What is the missing information?</h3>

This problem is incomplete, but researching it on the internet, the function used is $y = \sqrt{x + 2}$ .

<h3>Is it a function?</h3>

For $y = \sqrt{x + 2}$ , each value of x is associated with only one value of y, that is, the graph has <u>no vertically aligned points</u>, hence it is a function.

<h3>Is the function one-to-one?</h3>

Each value of y is also associated with only one value of x, that is, the graph has <u>no horizontally aligned points</u>, hence it is a one-to-one function, and the correct statement is given by:

A. it us a one-to-one function.

A ball has been thrown into the air its distance from the ground is given by the function s(t)=-16t^2+96t+100

slega [8]

Answer:

For t=3 sec the velocity change from positive to negative

Step-by-step explanation:

we have

$s(t)=-16t^2+96t+100$

This is the equation of a vertical parabola open downward (the leading coefficient is negative)

where

s(t) is the distance in feet

t is the time in seconds

We know that

To find out when the velocity change from positive to negative, we need to determine the turning point of the quadratic equation

The turning point of the quadratic equation is the vertex

Convert the quadratic equation into vertex form

$s(t)=-16t^2+96t+100$

Factor -16

$s(t)=-16(t^2-6t)+100$

Complete the square

$s(t)=-16(t^2-6t+9)+100+144$

$s(t)=-16(t^2-6t+9)+244$

Rewrite as perfect squares

$s(t)=-16(t-3)^2+244$

The vertex is the point (3,244)

therefore

For t=3 sec the velocity change from positive to negative
