domain of x^2-8x+7

domain

x^{2} - 8 x + 7

- \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

p er p e n d i c u l a r y = x + 10, (3, - 6)

m o n o t o n e x^{2} - 4

in v erse y = x + 6

d o main f (x) = \frac{1}{4 + x}

in v erse f (x) = \frac{5}{6} x + \frac{5}{3}
