extreme f(x)=2x+1,x<=-1

extreme points

f (x) = 2 x + 1, x \leq - 1

Maximum (- 1, - 1)

Solution steps

Find the critical points:

x = - 1

Domain of

2 x + 1, x \leq - 1 : x \leq - 1

Find intervals:

Increasing

: - \infty < x < - 1

Plug the extreme point

x = - 1

into

2 x + 1 \Rightarrow y = - 1

Maximum (- 1, - 1)

f (x) = lo g_{2} (\frac{1 + x}{1 - x})

f (x) = \frac{x ^{2}}{x - 9}

f (x) = \frac{x ^{3} - 4 x}{3 x ^{2} + 3 x - 6}

f (x) = 100 - 3 x

e^{x + 1}

What is the extreme f(x)=2x+1,x<=-1 ?
The extreme f(x)=2x+1,x<=-1 is Maximum(-1,-1)
