Answer:
y = (-2) 2^(x+1)
Step-by-step explanation:
Whenever x increases from by 1, y decreases by doubling (the negative value), so the exponent is -2
When x = -1, y = -2.
So the exponential equation (NOT linear) is
y(x) = -2*2^(x+1)
Check:
y(-1) = -2*2^(-1+1) = -2*1 = -2
y(0) = -2*2^(1) = -2*2 = -4
...
y(2) = -2*2^(2+1) = -2*8 = -16
all good.
Since we know that dilation of a figure changes all sides of a figure by same factor.
Let us find out factor of dilation of our figure.
We will find side length QR of our quadrilateral QRST and its corresponding side QR' of quadrilateral Q'R'S'T'.
Let us find side length of Q'R'.
Let us compare both our side lengths to find factor of dilation,
Upon cross multiplication we will get,
We can see that Q'R' is of Q'R'. Therefore, our factor of dilation is .
Cross multiply
10(x-3) = 9x
10x - 30 = 9x
-1x = -30
X = 30
