What is the range of the following function: f(x)=-x^2+x^-1 if the domain is {-2, -1, 1}

postnew [5]

f(x)= -x^2 + x^-1

f(-2)= - (-2)^2 + (-2)^-1 = -4 - 1/2 = -9/2

f(-1)= - (-1)^2 + (-1)^-1 = -1 -1 = -2

f(1) = - (1)^2 + (1)^-1 = -1 +1 = 0

The range is { -9/2, -2, 0}

Find the pattern and find the next three items in the pattern. 1, 1, 2, 6, 24, 120

seropon [69]

The pattern is:
1, 1, 2, 6, 24, 120
v v v v v
x1 x2 x3 x4 x5
so the next one would be 720 bc 120x6
the one after that would be 5,040 bc 720x7
the last one would be 40,320 bc 5,040x8

You are getting the right one!

All the solutions to sin(x) is 0°,180°,360° as you've chosen

You can refer to the graph for reference^
