1. TRUE - anything is symmetric about its axis of symmetry
2. FALSE - they open up or down, depending on the sign of "a"
3. TRUE - the x-coordinate of the vertex is -b/(2a). Its y-coordinate is f(x) at that point.

Answer:
228 cm
Step-by-step explanation:
the average is calculated as
average = , then
= 140 ( multiply both sides by 10 to clear the fraction )
sum = 1400
let the height of new pupil be x , then
= 148 ( multiply both sides by 11 )
sum + x = 1628 , that is
1400 + x = 1628 ( subtract 1400 from both sides )
x = 228
height of new pupil is 228 cm
