The function below models the correlation between the number of hours a plant is kept in sunlight (x) and the height (y), in mm, to which it grows: y = 2 + 4x what does the y-intercept of this function represent?

Y intercept of this function is 2 which is the height of a plant at the time x = 0 or the height of a plant when kept in sunlight.

Step-by-step explanation:

In the given function y = (2 + 4x), x is the number of hours a plant kept in sunlight and y is the height in mm.

Since this equation is in the form of equation of straight line y = mx +c in which m denotes gradient of the line and c is y intercept.

In y = 4x + 2, y intercept of the equation is 2 which means when a plant was kept in sunlight its height was 2 mm.
