Me with this. i thought the answer was 9 but i was wrong.

I think the point k may be the centroid of the triangle, so that point would be 2/3 of the way from the vertex to the opposite side. If the ENTIRE length of AP is 18, then point K would be at the 2/3 x 18 = 12 mark. So if you're looking to find KP, it would be (18-12) = 6.

Sketch the graph of y=7x

Reflect the graph across the y-axis to show the function y=7^-x

Stretch the graph vertically by a factor of 3 to show the function y=3x7^-x

Shift the graph up 2 units to show the function y=3x7^-x +2
