I have a question about math I have a problem like this where

My bad the value where it starts declining is 5

>>201910
>>201912
What exactly is the problem?

>>201915
It says write the equation for this graph. The answer would be something like square root of x +/- or×/÷ by a number would make it decline like that

It needs to look like this but instead of the slope increasing it needs to decrease

Try messing around with a hyperbola, it looks similar to 1/x + 0.25

Do you have exact values for the approximate curve, if so it is easy to get an equation.

>>201962
No I wasn't given a numer and did I have to solve for an exact value either

>>201964
Those words should be number and didn't

>>201910
looks like f(x)=x^(-1/2)

>>201978
>>201912
then try with f(x)=(x-5)^-1/2
