Answer:
1 The terms 4x3 and 8x have a common factor.
2 The terms 4x3 and – 6x2 have a common factor.
5 The polynomial can be grouped in different ways to factor by grouping.
Step-by-step explanation:
The rate of change is given by the coefficient of x in the <em>cost function</em>. Hence, the rate of change of cost in the function is 2.5
<u>Given the </u><u>cost</u><u> function :</u>
<u>Expanding the function and expressing in slope intercept form</u>:
y = 5.75 + 2.5x - 5
y = 2.5x + 2.75
Therefore, the slope of the function is 2.5 ; which ubsthe rate of change of the cost function.
