Question

Graph the function y = |8 - 2x| + 3. Which is a point on the function? (6.2, 7.4) (7.8, 11.2) (8.6, 6.8) (9.6, 7.3)

Answer 1

For this case we have the following function:
 $y = | 8 - 2x | + 3$
 The first thing you should do is graph the function to see the behavior.
 When observing the graph (in the attached image) we observe that the following point belongs to the graph:
 $(6.2, 7.4)$
 To prove it, let's evaluate the point in the function:
 $7.4 = l 8 - 2 (6.2) l + 3 7.4 = l 8 - 12.4 l + 3 7.4 = l -4.4 l + 3 7.4 = 7.4$
 The equation is fulfilled and therefore the point belongs to the graph.
 Answer:
 (6.2, 7.4)
