inflection f(x)=(7-2x)e^x

Solution

inflection points

f (x) = (7 - 2 x) e^{x}

Solution

(\frac{3}{2}, 4 e^{\frac{3}{2}})

Solution steps

f^{''} (x) = e^{x} (- 2 x + 3)

Find intervals:

Concave Upward

: - \infty < x < \frac{3}{2},

Concave Downward

: \frac{3}{2} < x < \infty

Plug

x = \frac{3}{2}

into

(7 - 2 x) e^{x} : 4 e^{\frac{3}{2}}

(\frac{3}{2}, 4 e^{\frac{3}{2}})

Popular Examples

slope ofintercept 5x-4y=12 slope intercept

5 x - 4 y = 12

domain of f(x)=sqrt(5x-1)domain

f (x) = 5 x - 1

slope of 2x+3y=4 slope

2 x + 3 y = 4

periodicity of f(x)=-5cos(4x)periodicity

f (x) = - 5 cos (4 x)

inverse of f(x)=3^x-2 inverse

f (x) = 3^{x} - 2
