Hey there!
A parent function is the most basic function in any group of functions. For example, f(x) = x^2 is the parent function for quadratic functions, and y = x is the parent function for linear functions. When there's nothing added, subtracted, multiplied, or divided to the function.
For A, we see that we're multiplying 2 times 3^x, and since this is not any alternation of any parent function or any parent function in particular, we can rule it out.
For B, we see that 3 is being added to x^2, so it cannot be a parent function.
For C, we see that 2 multiplied to e, therefore it cannot be the mot basic function.
Finally, for D, we see a function that looks similar to the quadratic parent function and is very simple itself. Any alterations to this is any other quadratic function
Your answer is D.
Hope this helps!

Answer:
A. quadratic
Step-by-step explanation:
the four points forms a curve that is parallel (parabola). quadratic is the shape of a curve like that
and exponential is only a curve
linear is like a straight line
Answer:

So, we have:
Answer:
Step-by-step explanation:
Let the co-ordinates of B be 
If a point 
is a mid-point of line segment AB with 
and 
, then:
Here, is 
is 
.
So, 
Plug in the formula and solve for unknowns.
Therefore, the co-ordinates of point B are
