Answer:
f'(x) = 5x^4 + 2x + 3x^2
Step-by-step explanation:
To find the derivative of this equation we can do two things.
One method is to use the product rule, which states that when f(x) consists of two functions multiplied to each other (meaning f(x) = g(x) * h(x)), the derivative is f'(x) = g'(x)*h(x) + g(x)*h'(x). In simple language, the derivative is found by finding the derivative of x² + 1 and multiplying it with the normal function of x³ + 1, after which you add the product of the nnormal function of x² + 1 and the derivative of x³ + 1.
it might be clearer when I show you:

If you are not familiar with this rule you can first write out the function and then use the basic rule:

If you need any further help please say so in the comments! I hope this helps! If the steps seem complicated, I suggest you could revise expanding brackets (the first step of the second method) and the basic rules of deriving, but feel free to reach out if you struggle afterwards still
Answer:
15 - 3 (expression)
15 - 3 = x (equation)
Step-by-step explanation:
A <u>central</u><u> tendency</u> is a value that describes the center of a data set and includes the mean, median, and mode.
And just in case you don't know:
Mean is the sum of all the numbers divided by how many numbers there are. Basically the average.
Mode is the number that occurs the most times.
Median is the middle number when you write the numbers from lowest to greatest.<u />
