Hey there!
The range of a function consists of all the y values the function has in its graph.
Notice in the graph your y values in the function range from 3 to infinity since the graph goes on infinitely upwards and then decreases to a steady y value of 3.
Therefore, your range in interval notation would be [3,∞) since the value of three is included.
Hope this helps and have a wonderful day! :)
Answer:
Step-by-step explanation:
solving for dy/dx
multiply the equation out to remove parentheses
now differentiating in terms of x ()
isolating dy/dx to one side
Your factors are (x+7)(x-5)(x+3)
multiply the first 2 to get (x^2 + 2x - 35)(x+3)
Now multiply in the 3rd one
x^3 + 2x^2 - 35x + 3x^2 + 6x - 105 now combine like terms
x^3 + 5x^2 -29x - 105 or A
