Answer:

Domain x ∈ R

Range y ∈ R

Step-by-step explanation:

Since the radical function have its exponential odd, there are no restrictions in what result should have in order to not obtain a complex value, that is why the domain is every real number (x ∈ R)

Now, to obtain the range, we have to determine possible values for 'y' variable. Since there are no restrictions in domain, and the function y= $\sqrt[3]{x}$ doesnt have limits, we can say that y also belongs to all real domain.

Dicriminant of x² – 49 = 0

Mama L [17]

Answer:

196

Step-by-step explanation:

The discriminant (Δ) is given by:

$\Delta = b^2-4ac$

Where the polynomial is in the form:

$ax^2+bx+c=0$

In this problem, a = 1, b = 0, and c = -49. Thus, plugging it into the formula:

$\Delta = 0^2-4(1)(-49) = -(-196) = 196$

Thus, the discriminant of x² – 49 = 0 is 196.

NORMAL DISTRIBUTIONS AID?

kykrilka [37]

Those are the ranges for one tandard deviation below the mean and one standard deviation above the mean, and we know that 68% of the data falls in that range, so the probability that a randomly chosen worker makes that much is 68%
