domain of ln(3.9x+3.8)-3.7

domain

ln (3.9 x + 3.8) - 3.7

x > - \frac{38}{39}

Interval Notation

(- \frac{38}{39}, \infty)

Solution steps

Find positive values for logs:

x > - \frac{38}{39}

The function domain

x > - \frac{38}{39}

f (x) = \frac{3 x + 2}{4 x - 20}

f (x) = \frac{3 x + 1}{x ^{2} - 1}

f (x) = x^{2} - x^{4}

y = x^{2} - 3 x - 4

y = 4 x - \frac{1}{5}
