domain of f(x)=(8x-1)+(-7x^2)

domain

f (x) = (8 x - 1) + (- 7 x^{2})

- \infty < x < \infty

Solution steps

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

- \infty < x < \infty

f (x) = \frac{4 x ^{2} - 7 x - 2}{x ^{2} + 1}

(1, - 1), (5, 3)

m = - 1, (- 5, 1)

f (x) = x^{2} + 4, x \geq 0

f (x) = \frac{( 6 x ^{2} - 5 )}{( 2 x ^{2} + 6 )}

What is the domain of f(x)=(8x-1)+(-7x^2) ?
The domain of f(x)=(8x-1)+(-7x^2) is -infinity <x<infinity
