Explain how you determine the sign of your answer when you raise a negative base to a power.

If the power is even number sign will be positive.

If the power is odd number sign will be negative.

Example:

-2²  = -2 * -2 = 4

-2³  = -2 * -2 * -2 = 4 * -2 = -8

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
