Sagot :

We need to find which function doesn't have a domain for all real numbers.

for a.

[tex]f(x)=\sqrt[]{x}-1[/tex]

When we have a square root " The domain is all values of x results in a radicand that is equal to greater than zero"

So the domain, in this case, is x≥0.

b.

[tex]-x^3+4x[/tex]

x can take any real number because we don't have restrictions.

c.

[tex]-\text{ l x-5l +1}[/tex]

We have an absolute value but x can be any real number.

d.

[tex]\frac{1}{2}\sqrt[3]{x+6}[/tex]

The cube root can be used for real numbers, so the function can take for x all real numbers.

The only function that doesn't have a domain of all real numbers is option a.
