Which of the following is a quadratic function
​

A quadratic a function has a form of,

The first function has a term which doesn't fit the profile of a quadratic function. The highest exponent on x inside a quadratic function can be 2, but here we have 3 so this is not a quadratic function, but rather a cubic function.

The second function fits the form of a quadratic function perfectly.

The third function is a bit tricky. While technically the third function could be considered quadratic if the leading term would be something like and we did't even see it written out because multiplying with 0. But when we specified the form of a quadratic function, we strictly said that the number before aka cannot equal to zero. So the last function is not a quadratic function but rather a linear function.

Hope this helps :)

step-by-step explanation:

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
