The answer is D) y = 3x^2 - 2, because the x is squared, making the function a quadratic function. Quadratic functions will be in the shape of a parabola (a u or upside down u).
Meanwhile any function whose degree (highest exponent of x) is one is a linear function. It will have be a straight line.
Say you have the number:
3,347
You can round it to the nearest thousand by figuring out whether 347 turns out to be closer to 0 or 1,000. If it's closer to 0, you round to the nearest thousand by producing the result 3,000. Since 347 is closer to 0, it would be incorrect to round the number 3,347 to the nearest thousand by producing the result 4,000.
In this case you round to the nearest thousand by producing the result 3,000.
Answer:
4(x + 1) and 4(x - (-1))
Step-by-step explanation:
4(-1 + 1) = 4(0) = 0
(4 (-1) + 5) = -4 +5 = -1
4(-1 - 1) = 4(-2) = -8
(5 - 4(-1)) = 5 + 4 = 9
4(-1 - (-1)) = 4(0) = 0
4 (-1 + (-1)) = 4(-2) = 8
