The function is given by the formula y = 2x + k. Find the value of k if it is known that the graph of this function belongs to point A (1; 5)
Since the graph of the function given by the formula y = 2x + k belongs to point A with coordinates (1; 5), then in order to find the value of k, we substitute the coordinates of point A (1; 5) into this function y = 2x + k.
2 * 1 + k = 5;
2 + k = 5;
k = 5 – 2;
k = 3.
Answer: k = 3.
