there is a 50% chance of landing on either heads or tails
The last choice, do an is the x value so you would look at the x values which is -4, 6. And range is the y values so the highest y value and the lowest. Which is -5,4. So you answer is the last option
The value would just be the answer which is 104
Answer:
Identity
Step-by-step explanation:
When you factor this quadratic (or any polynomial, for that matter), what you get are the zeros of the function. When the object is on the ground, its height is 0. The zeros of a function are where the graph goes through the x-axis. Where the graph goes through the x-axis, the y value is 0. Using the quadratic formula to factor this gives you zeros of t = -1 and t = 7. The two things in math that will never EVER be negative are time and distance/length, so we know that object will hit the ground 7 seconds after it is thrown.
