Question

passing through (-1,3) and (4,3)

Answer 1

What is passing through them? A line? A curve? A car? Ghosts...?

Answer 2

If you can give us/me some more details, I can probably can help you with this one, I love graphs.

Answer 3

They are asking us to find the function that passes through those two points.

@FeoNeo33 This is actually enough information.

Answer 4

Your best bet is a quadratic function.
Let our mystery function f(x):=ax^2+bx+c.
We solve the system
\[\begin{cases}
3=a+b+c \\
3=16a+4b+c
\end{cases}\]
We find that a, b, and c need to satisfy
\[15a+3b=0\\
\Rightarrow 5a+b=0\\
\Rightarrow b=-5a\]
Now if we had one more point we could figure out precisely what a, b, and c are.

Answer 5

There's not enough information to determine what type of function exactly.
Like, you could have a basic linear function y=3, or maybe its a set of quadratic functions like determined above. He'd have to specify what we were looking for to make an accurate answer. It's sometimes dangerous to assume things. :P
