Which function is a quadratic function?
y – 3x2 = 3(x2 + 5) + 1
y2 – 7x = 2(x2 + 6) + 7
y – 2x2 = 6(x3 + 5) – 4
y – 5x = 4(x + 5) + 9

Correct answer A

Step-by-step explanation:

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.
