Find the vertex by using the formula -b/2a
To find a and b, we must know that a and b are located at y = ax^2 + bx + c.
We find that b is 4 and a is 1 by looking at the given quadratic function.
The answer is A. -4/2(1) because the question is looking for the correct steps to find the answer.
<h3>
Answer: (1, -2)</h3>
Explanation:
Writing f(1) = -2 means x = 1 and y = f(x) = -2 pair up together
So we have (x,y) = (1, -2) as the point on the f(x) curve.
Answer:
198
Step-by-step explanation:
If you take any 3-digit number and change the numbers around and subtract them you will always get 198.
The answer is B. Flipping a coin does not influence your next flip. Also, the probability is 1/2*1/2*1/2, or 1/8.
The two sales people for a local advertising firm are Trinity and Jason.
