What is the range of the function y=1+2 sin (x-pi)

1 answer:

3 0

The sine has a range -1 to +1 so y goes from 1+2(-1) to 1+2(1) = -1 to 3

Range: -1 ≤ y ≤ 3

You do Pi×Radius^2
so 24×Pi=75.4
then 75.4÷2=37.7

Answer:

Option B) $y = (1.31)(2.8^{x})$ is the correct option.

Step-by-step explanation:

<em>Exponential function is the one where, a constant is raised to the power of x, a independent variable.</em>

Here, only option B and D are such exponential functions, while option A is linear and option C is quadratic in nature.

Now, to verify which option is correct, we will input the values and check which has the least difference between the given values.

Or we can use the cost function,

$J = \frac{((y(i))-y)^2}{2m}$ , to find which function has the least error.

By applying the above results,we find Option B is correct.
