Answer: g(x) = f(x-2)

Step-by-step explanation:

When plugged into desmos, g(x) = 1/4(2^x) - 4

g(x) = f(x-2) is the only equation that lines up with this equation I stated above.

Note: if you try to do this yourself on desmos graphing calculator, make sure to add f(x) first (f(x) is: f(x) = 2^x - 4).

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is given by

f ( x ) = 3x - 7

Now , substituting the value of f ( x ) = 20 , we get

when x = c

f ( c ) = 3c - 7

The value of the equation f ( c ) = 20

Substituting the value in the equation , we get

3c - 7 = 20

On simplifying the equation , we get

Adding 7 on both sides of the equation , we get

3c = 27

Divide by 3 on both sides of the equation , we get

c = 9

Therefore , the value of the variable c = 9

Hence , The value of c so that the function f ( c ) = 20 is when c = 9
