domain of f(x)=4+8x-5x^2

domain

f (x) = 4 + 8 x - 5 x^{2}

- \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

f (x) = x + 9 - 2

f (x) = 2 x + 30

f (x) = - 3

x + 5

y = x^{\frac{9}{2}} - 7 x^{2}
