Answer:
The second and third answers are correct.
Step-by-step explanation:
This is a upwards opening parabola. It has no maximum. It has a minimum at ( 1,-4).
The first answers is incorrect.
A function is increasing when it goes up. It is increasing from 1 to the right or when x>1 . It is also increasing from - infinity to 1 so x <1
The second answer is correct.
The y intercept is where it crosses the y axis. This is at the point x = -2
The third answer is correct.
All points on a graph are solutions to the function. If the function is set equal to zero, then this has two real zeros.
The fourth answer is false.
A constant rate of change means that it is linear. This is a parabola. A parabola increases as x^2 not x, so it is not a constant rate of change
The fifth answer is not correct.
The range is the values that y can take.This says y must be less than or equal to -4. That is not true. y≥ -4.
The sixth answer is not correct.
Use the Pythagorean theorem:
x = √(12^2 + 9^2)
x = √(144 + 81)
x = √225
x = 15
Answer:
Sean got 63/81 questions right as a fraction.
Step-by-step explanation:
Sean got 63/81 correct. If there was a total of 81 questions, you put that as your denominator.
Now ask yourself: Can you simplify?
Yes you can.
You divide each number from the fraction by 9.
63 / 9 = 7
81 / 9 = 9
7/9 questions that Sean got correct.
If you also want a percentage + grade, Sean would get 77% which would be a C+
