Functions are a set of points that show how dependent variables change through independent variables.
Defining a Function
In functions, each x-value is assigned to exactly one y-value. This means that x-values do not repeat. So, if there is one x-value more than once in a set, then it cannot be a function.
For example, set B has the x-value 3 and 4 repeated twice. Thus, it does not represent a function.
Graph of a Function
Functions can also be defined through a graph. Just like with coordinate points, x-values do not repeat on the graph. You can use the vertical line test to see if a graph is a function. If you can draw a vertical line at every point on a graph without it ever intersecting with the graph more than once, then it is a function.

Answer:
We get t= 7.22 and t=0.28
The correct options are Option A and Option G
Step-by-step explanation:
The height h of toy rocket at time t seconds after launch is given by the equation 
We need to find how many seconds until the rocket is 40 feet?
We are given height of rocket h(t) = 40 feet
and we need to find time t
Using the equation we can find time t
We have h(t)=40
Now, we will solve the quadratic equation using quadratic formula: 
We have a =16, b=-120 and c=32
Putting values and finding t
So, we get t= 7.22 and t=0.28
The correct options are Option A and Option G
