Write an equation to represent the data shown in the table below.

x y
-2 152
-1 76
0 38

Step-by-step explanation:

x       y

-2      152

-1       76

0       38

From the value of y we can see that the value are decreasing

152/2= 76

76/2= 38

So the table represents exponential equation

y=ab^x

Plug in x=0 and y = 38

38=ab^0

38=a

now find out b

Plug in -1 for x  and 76 for y

76= ab^(-1)

76=38b^-1

b=1/2

So equation becomes

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
