Which expression corresponds to this graph?
Elodia [21]

Answer: Choice A

The number line graph is visually showing every number that is 19 or smaller; hence x \le 19

Note the use of a closed or filled in circle at the endpoint (in contrast to an open circle). This indicates we are including the endpoint 19 as part of the solution set, and that's why we go for "or equal to" as part of the inequality sign.

Given: y = 2x^2 - 32x + 56

1) y = 2 [ x^2 - 16x] + 56

2) y = 2 [ (x - 8)^2 - 64 ] + 56

3) y = 2 (x - 8)^2 - 128 + 56

4) y = 2 (x - 8)^2 - 72 <----------- answer

Minimum = vertex = (h,k) = (8, - 72)

=>  x-ccordinate of the minimum = 8 <-------- answer
