An easy this to do is use desmos... an online graphing site that will allow you to graph the curves and points...

The alternate method is to subsitute each point into each equations...
I just did (-2, 2) into A... that point is not on the curve.. that would be the hard way. Subsituting x = -2 y = 18 so (-2, 2) isn't on the curve.
so eliminate A
repeat the process with B etc is (-2, 2) in on the curve, then select the next point and check.
That's why graphing is easier
In the given figure there are 3 graphs
The line represents a linear function
The parabola represents a quadratic function
The third graph which approaches to the negative part o the x-xis is the exponential function
The x-intercept of the line is (-2, 0)
x-intercept means intersect the x-axis at point (-2, 0)
There is only one graph that intersects the x-axis at (-2, 0)
It is the line, the linear function h(x)
The range is between 0 to infinity (0, ∞)
The range is the values of y
There is only one graph that has all values of y over the x-xis
it is f(x) the exponential function
You would take the answer of the square root problem and find the number that you can multiply by its self that would make that answer correct.
Since log(0) is undefined, we can assume that there is a vertical asymptote there. So, to make the function log(0), x needs to be -3. There is a vertical asymptote at x=-3. Since the function has not been shifted anywhere, or flipped vertically/horizontally, the answer would most likely be A.
