What is the xintercept of yxexSolutionGiven function is y x
What is the x-intercept of y=-x+e^x
Solution
Given function is y = -x+e^x
To find x intercept we substitute y =0
When y =0
we have x + ex=0
Let f(x) = x+ex
f(0) = 1
f(-1) = -1.3679
So there is a root between -1 and 0
f(-0.5) >0
So root lies between -0.5 and -1
f(0.75) <0
So rootlies between 0.5 and 0.75
Thus we find x intercept as a value =-0.567
x intercept =-0.567 upto 3 decimals.
