Solving fx = gx for mathematics?

f(x) = 2 - x^(2)

g(x) = sine^(x)

The 2 graphs are between -2 and 2.

Solve for f(x) = g(x)

Also, i was wondering if there was a way to do this on the calculator by making the graphs or something.



you have to plot both f(x) and g(x) on a graphic calculator. (a calculator capable of plotting graphs)

alternatively you can use an online graphic calculator like this one:…

then for f(x)=g(x), get the intersection points

which is (-1.3173, 0.2646) and (1.6757, -0.8081)


x ~= 1.0644


(-1.3173, 0.2647), (1.6757, -0.8078)...................Ans by graphing calculator on line
