Choose the graph of y = -4 cot x.
1 answer:
Suppose y= cot x is our parent function then remember general rules of transformation.
1) y= -f(x), reflects the graph of f(x) across x-axis.
2) y= cf(x), stretches the graph of f vertically by factor of c , for c >1.
Now, apply these rules to y= -4 cot(x)
the -ve sign reflects the graph of cot(x) across x-axis and the number 4 will stretch it vertically by 4 units.
The graph of both parent function (y=cot x ) and transformed function (y= -4 cot(x)) are attached below.

Step-by-step explanation:
The geometric mean finds the typical value of a set of numbers through multiplication. To find the geometric mean of two numbers, you take the square root of the product of the two numbers.
So in this instance, multiply the two numbers together:
And take the positive square root of the product:
The geometric mean is different than the commonly-used arithmetic mean, which finds the central value of a set of numbers by dividing the set's sum total by how many numbers are in the set.
