Function f is an exponential function.

x      −1     1     3          5           7

f(x)     14    4   64     1024     16,234

We use exponential function y =ab^x

We find out factor b

When x=1 then y=4, so equation becomes 4=ab^1

When x=3 then y=64, so equation becomes 64=ab^3

Divide the second equation by first equation

\frac{64=ab^3}{4=ab^1}

16 = b^2

Take square root on both sides

So b = +-4

f(x) is increasing, so b= 4

Answer is 4

Please hellp find x y and z
melomori [17]

Answer:

angle x = 98

angle y = 82

angle z = 82

Step-by-step explanation:

angle y + 98 = 180; therefore, angle y = 82 degrees

angles z and y are alternate interior angles and are congruent (equal)

angle x is 98 degrees because angles x and y are same-side interior and their angles are supplementary (add up to 180 degrees)
