The range of the function f(k)=k^2+2k+1 is {25, 64}. what is the function’s domain?

The domain is [-9, -6] and [4,7]

Step-by-step explanation:

The range of the function is the output values which the function has on its graph. The function f(k)=k^2+2k+1 has a range of {25, 64}. Since these are the boundaries of the range, then the boundary of the domain will be the corresponding inputs which map to these values. Graph the function and identify the input values for f(k) = 25 and f(k) = 64.

Consider the point marked on the graph below. The x value of the furthest left point is the left boundary of the domain. The x value of the furthest right point is the right boundary of the domain. You'll notice the range is only a particular section of the complete the graph. This means there will be two sets for the domain.

The domain is [-9, -6] and [4,7].

b because it contains 40% of the possible results from the random list.

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
