Hi there, so for this problem we are given that the profit for this is that f of x is equal to 2 times x and this minus 1 .5.
00:20
So for part a of this problem we are asked to give the slope of the line defined by the equation.
00:28
So this slope is just the derivative of this function with respect to x.
00:34
So in this case, that will be just simply two.
00:40
Now, for part b of this problem, we are asking about to write the rate of change of the function in a sentence of interpretation.
00:54
So with this, we know that the profit is 2, which is the value that we obtain, this, by well, sorry, is increasing.
01:18
Okay, so that's a solution.
01:20
It is increasing because the value is positive.
01:23
Then it is increasing by two, that's a solution that we obtained from before.
