domain of f(x)=7x^2-12x+21

domain

f (x) = 7 x^{2} - 12 x + 21

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

8 x - 18

3 ln (x + 5) - 2

f (x) = 32 ln (x) - x^{2}

7 - 5 (x - 1)

y = \frac{7}{4 x - 1}
