From my knowledge, I would use the vertical line test instead of the horizontal line test. The vertical line test checks if something is a function, and the horizontal line test checks if an inverse function exists. (Correct me if I'm wrong, I haven't used this in a while.)
If I use the vertical line test:
A would fail because it intersects the vertical line more than once.
B would fail because the ellipse would intersect the vertical line more than once.
I can't see C too clearly, but from what I can make out of it, it doesn't pass the vertical line test because there are 2(?) lines and it intersects the vertical line more than once.
D passes the vertical line test because the parabola only intersects the vertical line at one point.
Hope I helped :)
Answer: Logarithmic
Explanation:
This curve is a reflection of the exponential curve over the line y = x, to show that it is the inverse of exponentials. We use logs to help isolate the exponent among other useful properties.
4 option is correct I think so
Answer:
![g(x)=(x-7)^2+5](https://tex.z-dn.net/?f=g%28x%29%3D%28x-7%29%5E2%2B5)
Step-by-step explanation:
Translation of f(x) by h units to the right and k units upward transforms it to ...
g(x) = f(x -h) +k
Here, you have f(x) = x^2, and (h, k) = (7, 5), so the transformed function is ...
g(x) = (x -7)^2 +5
