The function is given by the formula y = 18x. Specify the coordinates of two points A and B belonging to the graph of this function.
Let x = 1. Knowing that y = 18x, calculate y.
y = 18 * 1 = 18.
Coordinates of one point (1; 18).
We calculate the value of y at x = – 1.
y = 18 * (- 1) = – 18.
Coordinates of the second point (- 1; – 18).
Answer: (1; 18), (- 1; – 18) – two points belonging to the graph of the function y = 18x.
