For this case we have the following function:
f (x) = - 4sine ((pi / 6) x) + 5
We evaluate the function for x = 0
f (0) = - 4sine ((pi / 6) 0) + 5
f (0) = -4 * (0) + 5
f (0) = 5
We note that the result does not correspond to the table.
Let's rewrite the function:
f (x) = - 4cosine ((pi / 6) x) + 5
We evaluate the function for x = 0
f (0) = - 4cosine ((pi / 6) 0) + 5
f (0) = -4 * (1) + 5
f (0) = 1
The result corresponds to the table
Answer:
The student's mistake is to use the sine function instead of using the cosine function.
The correct function is:
f (x) = - 4cosine ((pi / 6) x) + 5
the required algebraic expression is:
Step-by-step explanation:
We need to write the algebraic expression of the sum of a number z divided by three and the number
Let the number be z
a number z divided by three:
the sum of a number z divided by three and the number:
So, the required algebraic expression is:
