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
Answer: y=−2x+1
Step-by-step explanation:
F(x)=3^x
because: when x=1; f(x)=3^1=3 (pair (1;3)
x=2; f(x)3^2=9
x=3; f(x)=3^3=27
x=4; f(x)=3^4=81
Answer:
there the same ratio because there both offering the same ratio of of there number
3x10=30 ratio : 10
2x10=20 ratio: 10
