Graph the function y = 2.2 – |0.4x + 1|. what are the coordinates, to the nearest tenth, of the maximum of the graph? (2.5, 2.2) (–2.5, 2.2) (0, 3.2) (3.2, 0)

vertex is (-2.5, 2.2)

Step-by-step explanation:

Graph the function y = 2.2 – |0.4x + 1|

the function can be written as

Maximum of the graph lies at the vertex

LEts find out the vertex

The vertex form of the equation is

where (h,k) is the vertex

solve for x

Subtract 1 on both sides and then divide both sides by 0.4

the value of h = -2.5  and the value of k= 2.2

So vertex is (-2.5, 2.2)
