What is the range of the function of the graph​
Alex_Xolod [135]

Answer : Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

sleet_krkn [62]

The average fraction of students in the two classes who went on the field trip is 11/16

<h3>What is the average fraction of students in the two classes who went on the field trip?</h3>

The given parameters are:

Class 1 = 3/4

Class 2 = 5/8

The average is calculated as

Average = 1/2 * (Class 1 + Class 2)

So, we have

Average = 1/2 * (3/4 + 5/8)

Evaluate

Average = 11/16

Hence, the average fraction of students in the two classes who went on the field trip is 11/16

Find f'(x) for f(x)=cos^2(5x^3).
-BARSIC- [3]

d/dx cos^2(5x^3)

= d/dx [cos(5x^3)]^2

= 2[cos(5x^3)]

= - 2[cos(5x^3)] * sin(5x^3)

= - 2[cos(5x^3)] * sin(5x^3) * 15x^2

= - 30[cos(5x^3)] * sin(5x^3) * x^2

Explanation:

d/dx x^n = nx^(n - 1)

d/dx cos x = - sin x

Chain rule:

d/dx f(g(...w(x))) = f’(g(...w(x))) * g’(...w(x)) * ... * w’(x)
