I can eyeball points (1/2, 8), (1,4), (2,1), (3,1/4)


The pattern is each increment of 1/2 in x divides by two.


f(x) = (\frac k 2)^{2x} = \frac{k}{4^x}


Any of the points give k=16


f(x) = 16( 4 ^{-x} )  = 4^{2-x}


Check: x=1/2 4^(3/2)=2^2=8 good


x=1 4^(2-1)=4 good


x=2 4^(2-2)=1 good


x=3 4^(2-3)=1/4 good

Had to do it to em
ohaa [14]

Answer:

A is the correct answer

Step-by-step explanation:

When x =4 and y =-5, and you want to evaluate equation -3x+2y, you just have to apply it into the equation.

We got the equation as:

= -3x + 2y

= -3*4 + 2*(-5)

= -12 + (-10)

= -12 - 10

= -22

Hope this help you :3
