Answer:
Explanation:
I'm not sure what exactly you're trying to do.
If it is to match the equations to one of the curves, then simply opt for a few x values and plug into the equations to see if the y values match.
I can tell you right off that the two equations with negative exponents (options 2 and 4) can be eliminated straight off as those would be asymptotic to the positive x axis ± 1
Of the other two options, option 1 plots to the red dashed curve.
There is no equation option which plots to the black curve which appears to be a plot of y = 2ˣ
