Which exponential function is represented by the values in the table?

f(x) = 3(2x)

f(x) = 2(2x)

f(x) = 3(3x)

f(x) = 2(3x)

The function .

Step-by-step explanation:

Given : Table for x and f(x).

To find : Which exponential function is represented by the values in the table.

Solution :  Let the exponential function that is represented by the values in the table be of the form,

On plugging the values from table (0,3)

we get ,

3 = a.

tex]f(x) = 3( {b}^{x} )[/tex]

To find value of b we substituting other point from table (1,6)

tex]6 = 3( {b}^{1} )[/tex].

2 = b.

Therefore , the function .

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

answer: .64
