Question

Which function best represents a sine curve that repeats every 12 units and has a maximum of 42 and a minimum of 4?

Answer 1

Given:

n=12, maximum and minimum values are 42 and 4 respectively.

Required:

We have to find the curve which satisfy the given information.

Step-by-step explanation:

Here we have to use the try and error method means we have to eliminate the option which is incorrect.

first of all for option A and D are eliminate because in these two we get minimum value is not 4

`23(-1)+19=-4`

here the minimum value of sine is -1

now we have to find between B and C

here we have value of n is 12

for C

we get the maximum value 42 and minimum value 4 because in C we can get the value for sin function -1

Final Answer:

C
