How do you find the equation of each function? Function A is f(x)=3x^2 and Function C is f(x)=18x-16. How do you get those? And then how do you get the equation for Function B? Thanks!

--- Function A

--- Function B

--- Function C

Step-by-step explanation:

Solving (a): Equation of Function A

An exponential equation is represented as:

From the graph of function A,

For:

becomes

For:

becomes

Substitute 1 for a

becomes

Replace y with f(x)

Solving (b): Equation of Function B

A quadratic equation is represented as:

From the table of function B,

For:

becomes

For

becomes

becomes

So, we solve for a, b and c in:

Make c the subject in

Substitute in and

Divide through by 3

Solve for a and b in: and

Subtract both equations:

Divide both sides by -1

Substitute 1 for a in

Subtract 9 from both sides

Substitute and in

So, the equation is:

Replace y with f(x)

Solving (c): Equation of Function C

This is calculated using:

Where

-- the first term

d = the difference between successive terms

So, we have:

answer: i believe its b. if you sound out the sentences that sounds wrong.

no ,sorry if you needed it but you can ask and try to see if any one will anwser ,
