domain of f(x)=-0.0625(5)^2+3(5)-20

domain

f (x) = - 0.0625 (5)^{2} + 3 (5) - 20

- \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

\frac{5}{x ^{3}}

f (x) = \frac{x + x}{x}

f (x) = lo g_{x - 2} (- 2 x + 7)

f (x) = x^{2} = 4, x \leq 4

What is the domain of f(x)=-0.0625(5)^2+3(5)-20 ?
The domain of f(x)=-0.0625(5)^2+3(5)-20 is -infinity <x<infinity
