domain of f(x)=sqrt(t-25)

domain

f (x) = t - 25

t \geq 25

Interval Notation

[25, \infty)

Solution steps

Find non-negative values for radicals:

t \geq 25

The function domain

t \geq 25

f (x) = \frac{4}{2 + 3 \cdot 2 ^{x}}

\frac{x ^{2} - 8}{4} + 9 x^{2} + 8

f (x) = 25 - x^{2} + - (x - 2)

f (x) = \frac{x ^{2} - 10}{x ^{2} - 9}

\frac{x ^{2}}{4 - x ^{2}}
