Y-INTERCEPT

The y-intercept is where the equation/curve/parabola cosses the y-axis.
The y-axis is where x = 0. (The x-axis is where y = 0)
To find the y-intercept:

The y-intercept must be at (0, 10)
X-INTERCEPT (ROOTS/SOLUTIONS)

We need to use the quadratic formula
The quadratic formula helps us find what values of  make the equation = 0
 make the equation = 0
Quadratic formula: 

The x-intercepts are at:

 
        
             
        
        
        
Answer:
13 buttons
Step-by-step explanation:
The first step is to add the buttons received by the 6 students.
= 10 + 14 + 15 + 12 + 13 + 14
= 78 buttons 
Therefore the number of buttons received by each students can be calculated as follows
= 78/6
= 13 buttons
Hence each student will receive 13 buttons

Answer:
Step-by-step explanation:
Each point of function b(x) is shifted by rule 
x -----> ( x - 2 ) 
and 
y -----> (y + 3) 
( - 1.5, 0) ------> (- 3.5, 3) 
(- 1, - 1) -----> ( - 3, 2) 
(0, - 2) ------> ( - 2, 1) 
(1, - 1) -----> ( - 1, 2) 
(2, 3) -----> (0, 6) 
(4, 7) -----> (2, 10)
