Final Answer:
This quadratic function meets the given conditions:
, and
for
. So, the correct option is
.
Explanation:
In the provided conditions, we aim to find a function that adheres to specific criteria for its derivative. The quadratic function
is a suitable choice. Firstly, the requirement
suggests a possible turning point at (x = 2), characteristic of an extremum. This aligns with the quadratic nature of the function, where the coefficient of the
term determines concavity.
Secondly, the condition
indicates that the slope of the tangent line at the origin is 1. This implies an upward-sloping tangent at (x = 0), consistent with the positive coefficient of the
term, which dominates the behavior of the function for small (x).
Lastly, the requirement
implies that the function is monotonically increasing for positive (x), substantiating the positive leading coefficient in the quadratic term. In essence, the selected quadratic function satisfies the given conditions by exhibiting a turning point at (x = 2), an upward slope at (x = 0), and overall positive derivatives for
