Graph always uses a period (.) as decimals separator instead of comma.

If I copy the function as written, it contains two types of minus (- and –) but Graph only supports the first, which is the one found on your keyboard.

Graph will interpret

*-4,293 * 10^-3 x^4*as*-4,293*10^(-3x^4)*which of course is not what you want. You need to add a * to avoid that:*-4,293 * 10^-3 * x^4*You probably wanted

*0,9784*to be*0,9784x*

So we end up with this:

`f(x) = -4.293 * 10^-3*x^4 - 4.386 * 10^-3 * x^3 - 3.790 * 10^-3 * x^2 + 0.9784x + 3.468`

Alternatively you can write it like this, which uses another way to write scientific numbers:

`f(x) = -4.293E-3*x^4 - 4.386E-3 * x^3 - 3.790E-3 * x^2 + 0.9784x + 3.468`

f(x)= -4,293 * 10^-3 x^4 – 4,386 * 10^-3 x^3 – 3,790 * 10^-3 x^2 + 0,9784 + 3,468

Here's pictures of how it's supposed to look, and how it ended up looking in graph

btw, when there's no space between the numbers and the - it's because it's negative..

Thanks in advance, and sorry for wasting your time :)
