For brainliest y=x2−4x−1y=x2−4x+1y=−x2−4x+1y = x² + 4x + 1

The answer would be B or the Second choice

Step-by-step explanation:

As you can essentially plug in each X on the other side of Y, from there you can see if the equation will equal the Y.

y = x^2 - 4x + 1 Fits all the X's and equals the according Ys

1^2 - 4(1) + 1 = -2

2^2 - 4 (2) + 1 = -3

So on and so forth.

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

no not all of them.

step-by-step explanation:

some of them have a square base.
