Question

f (x) = xe−x Determine the y–intercept

Answer 1

f(x) = x $*$ e^-x

For y - intercept we substitute x = 0 and find the value for y.

y = f(x) = x $*$ e^-x

On substituting x = 0 in the above equation, we have

y = 0 $*$ e^-0

y = 0 $*$ 1

y = 0

Therefore, the y - intercept is equal to 0.
