Step-by-step explanation:
The vertex form of the equation for a parabola is given by
where (h, k) are the coordinates of the parabola's vertex. Since the vertex is at (1, -6), we can write the equation as
Also, since the parabola passes through (4, -7), we can use this to find the value for a:
or
Therefore, the equation of the parabola is
Answer: in explanation
Step-by-step explanation:
Rate is simplest form, so 3 napkins for 5 cents.
Unit rate is for 1 x value, so 1 napkin for 0,6 cents.
Answer:
{10, 20, 30, 40, 50, 60}
Step-by-step explanation:
The function is:
State that the tange of function is the set of all output values of a function. Therefore, the answer cannot be {1, 2, 3, 4, 5, 6} and . The answer is not because its output will always be a natural number and it's not stated in the answer, like I did above. The answer is {10, 20, 30, 40, 50, 60}
