domain of f(x)=2x-42

domain

f (x) = 2 x - 42

- \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) = 6 x - x^{2} + 7

y = 3 x

f (x) = - \frac{2163}{2333} x + \frac{4496}{2333}

f (x) = - 20 - x

- 2 x^{2} + 5
