domain of f(t)=cos(sqrt(t-2))

domain

f (t) = cos (t - 2)

t \geq 2

Interval Notation

[2, \infty)

Solution steps

Find non-negative values for radicals:

t \geq 2

The function domain

t \geq 2

\frac{8 x + 40}{x - 6}

f (x) = x^{2} + y^{2} + 2 x + 4 y + 4 = 0

y = lo g_{10} (8 - 4 x)

f (x) = - (x - 6)^{2} - 26

ln (t^{2} - 1)
