Answer:
It will grow '2d'
Step-by-step explanation:
Given,
The increment per day in the height of plant = 2 cm,
Total number of days = d,
Thus, the growth of plant in d days = growth of plant per day × number of days
Hence, the required expression that shows the growth of plant is,
Given the focus (h,k) and the directrix y=mx+b, the equation for a parabola is (y - mx - b)^2 / (m^2 +1) = (x - h)^2 + (y - k)^2.
