domain of f(x)=2x^2-x+1,(0<= x<4)

domain

f (x) = 2 x^{2} - x + 1, (0 \leq x < 4)

0 \leq x < 4

Interval Notation

[0, 4)

Solution steps

Set the domain to the given interval

0 \leq x < 4

The function has no undefined points nor domain constraints. Therefore, the domain is

0 \leq x < 4

\frac{7 x + 1}{8 - x}

y = \frac{cos ( x )}{x ^{2} - 5 x - 6}

x^{2} - 4 x, x < 5

f (x) = \frac{3 x ^{2} - 3 x - 6}{x ^{2} + 4 x + 4}

f (x) = \frac{10 x + 3}{4 - 3 x}
