Answer:
To find the x -intercept, set y=0 .
Therefore, the x -intercept is (−4,0) . To find the y -intercept, set x=0 .
−3x+2y↓−3(0)+2y2yy=12=12=12=6Tofindthey−intercept,setx=0.
Step-by-step explanation:
To find the x - and y -intercepts algebraically, use the fact that all x -intercepts have a y -value of zero and all y -intercepts have an x -value of zero. To find the y -intercept, set x=0 and determine the corresponding y -value. Similarly, to find the x -intercept, set y=0 and determine the corresponding x -value.

Step-by-step explanation:
Given:
Consider the height of the rocket, in feet after x seconds of launch is
To find:
The time at which the rocket will reach its max, to the nearest 100th of a second.
Solution:
We have,
It is a quadratic polynomial with negative leading coefficient. So, it is a downward parabola.
Vertex of a downward parabola is the point of maxima.
To find the time at which the rocket will reach its max, we need to find the x-coordinate of the vertex.
If a quadratic function is 
, then the vertex is
Here, 
.
So,
So, x-coordinate of the vertex is 4.75.
Therefore, the rocket will reach its max at 4.75 second.
