The graph of f(x) = 3 . 2*-3 is shown below. g(x) is a transformation of f(x).
DiKsa [7]

Answer: (c)

Step-by-step explanation:

Given

Function f(x) is 3\times 2^x-3

Also, g(x) is the transformation of f(x)

From the graph, it is clear that g(x) passes through the point (0,5)

Now check the option which satisfies the condition

option (c) seems to obey it

g(x)=3\cdot 2^x+2\\g(0)=3\cdot 2^0+2\\g(0)=3\cdot 1+2\\g(0)=3+2\\g(0)=5

Therefore, option (c) is correct.

The length of a rectangle is twice its width. If the perimeter of the rectangle is 54 in, find its area.
sergiy2304 [10]

Answer: 162 in²

Step-by-step explanation:

The factors of 54 are listed below:

  • 1
  • 2
  • 3
  • 6
  • 9
  • 18
  • 27
  • 54

18 and 9 are the two factors that when plugged into the equation below, equals 54:

l+l+w+w=P

This can also be written as:

(l*2)+(w*2)=P

So now that we have our two factors, we need to multiply them by each other to get our answer.

18 times 9 = 162

Our answer is 162
