Answer: √28

Solution:
The three squares form a triangle where the hypotenuse is 8 and the right side is divided into 6 and a.

So 8^2 = 6^2 + a^2
(Using the Pythagorean theorem)

64 = 36 + a^2
64 - 36 = a^2
28 = a^2
a = √28

What are the domain and range of the function f(x) = x^4-2x^2-4 ?
tatuchka [14]

Answer:

Think about what domain and range is. Domain is the x and range is the y.

Step-by-step explanation: What values of x can you put in this function? Is there any number you cannot use?? Then what y's will you get back? The best way to find out might be to graph it to look. Since it is an even function whose ends go up, all the y's will be greater than or equal to the y value of the vertex.
