domain of f(x)=ln(-2x^2-2x+40)

domain

f (x) = ln (- 2 x^{2} - 2 x + 40)

- 5 < x < 4

Interval Notation

(- 5, 4)

Solution steps

Find positive values for logs:

- 5 < x < 4

The function domain

- 5 < x < 4

f (x) = ln (26 - 9 x^{2})

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

f (x) = \frac{x}{x ^{2} + 12 x + 35}

f (x) = 1 - x ln (x + 2)

What is the domain of f(x)=ln(-2x^2-2x+40) ?
The domain of f(x)=ln(-2x^2-2x+40) is -5<x<4
