domain of f(x)=5x^2+1

domain

f (x) = 5 x^{2} + 1

- \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

x = - 4 (y - 7)^{2} + 7

y = - x^{2} + 8 x - 16

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

4 x^{2} - x - 3

f (x) = 65 x - 10
