What is 2 to the power of -2? My teacher said it does not equal -4… does it equal positive 4??
mihalych1998 [28]

Answer:

1/4

Step-by-step explanation:

2 to the power of -2 would be 1/4.

This is because 2 to the power of -1 would be 1/2. And the power of 2 would square the 2 as the denominator making it 1/4.

The reason -1 makes the 2 turn into a fraction is that to the power of 2 means 2x2, to the power of one means 2, The power of zero would therefore divide by 2 so 2/2 = 1 and so 2 to the power of -1 would be 1/2.

Graph the function f(x)=1.5x^2 and identify domain and range
seraphim [82]
Given:
f(x) = 1.5x²

Domain is all the values of x. 
Range is all the values of y.

x    y
1   f(1) = 1.5(1²) = 1.5(1) = 1.5
2   f(2) = 1.5(2²) = 1.5(4) = 6
3   f(3) = 1.5(3²) = 1.5(9) = 13.5
4   f(4) = 1.5(4²) = 1.5(16) = 24
5   f(5) = 1.5(5²) = 1.5(25) = 37.5

If we graph it, the following coordinates will be:
1st point (1,1.5)
2nd point (2,6)
3rd point (3,13.5)
4th point (4,24)
5th point (5,37.5)
so on...
