Question 121737
Since we have x as an exponent and it is also multiplied by some constant, there is no algebraic way to solve this. So a numerical approximation is the next best thing.


So if we graph {{{y=e^x + 2x}}} and {{{y=7}}}, we get



{{{graph(500,500,-10,10,-10,10,exp(x)+2x,7)}}} Graph of {{{y=e^x + 2x}}} (red) and {{{y=7}}} (green)



Now using the "intersect" feature on a calculator, we find that the two graphs intersect at the point (1.424, 7)



So the answer is  1.424 which means the choice is A)
