Answer:
, h(t) = 6t² +(-t) + 12 is a quadratic function .
Explanation:
Given : h(t) , g(t) ,k(t), h(t).
To find : Which function is a quadratic function .
Solution : We have given that different function ,
Quadratic function : A quadratic function is one of the form f(x) = ax² + bx + c, where a, b, and c are numbers with a not equal to zero.
We can see from given option option d has the degree 2 but all the option have degree 3 and 4 so, they can not be quadratic function .
Quadratic function have degree 2
Therefore, h(t) = 6t² +(-t) + 12 is a quadratic function .
