Check all that apply.
10, 18, 26, 34,..
DA. X,= 10 + 8(n- 1)
OB. X, =2 + 8n
OC. x- 8(n-1)
DD. Xp- Xp1 t8
DE. x, =X *(n- 1)vat

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
