Mi español no es muy bien pero yo pienso que es B.
Answer:
Step-by-step explanation:
y=4 times 1/2 to the power of x can be written symbolically as
4 4
y = 4(1/2)^x. This is the same as y = ------- or y = -------- * 2^(-x)
2^x 1
This function is a "decaying exponential."
A suitable table follows:
x 4(2^[-x]) x y
0 4(2^0) (0, 4)
1 4(2^1) (1, 8)
2 4(2^2) (2, 16)
and so on.
Its a dilation of 2, I believe ........
0.45 Isn't Equal To Any Of These Fractions But It Is Equal To 45/100
(4x-7y)(4x+7y)
4x times 4x= 16x^2
-7y times 7y= -49y^2
