Answer: Hey the answer is f(x)=4•(0.5)^x
Step-by-step explanation:
For this case what you should do is evaluate values of x in the function and verify that they meet the result of f (x) shown in the graph.
The answer is
f (x) = - 2lxl +1
notice that
f (1) = - 2l1l + 1 = -1
f (-1) = - 2l-1l + 1 = -1
Both comply with the value of f (x) shown in the graph
answer
f (x) = - 2lxl +1
Let the line segment BD be x, then sin A = x/15
or, x = 15sinA

The last option
X^2 -61 =20
X^2= 81x =9 x=-9
