I guss
value of x is -3/4
… z =w …angle v x w = angle z x y
It follows AAA SIMILARITY Relation
Answer:
y = -2·(1/2)^x
Step-by-step explanation:
The ratio of one table entry to the one before is ...
(-2)/(-4) = 1/2
so this is the <em>growth factor</em>.
The <em>multiplier</em> is the value of y when x=0, which is -2. So, the equation is ...
y = (multiplier)·(growth factor)^x
y = -2·(1/2)^x
_____
This can also be written using a negative exponent:
y = -2·2^(-x)
The Answer is B
