Given f(2) = 12, which of the following could be an equation of the function?
a.
f(x) = 8x – 2
b.
f(x) = 4x + 4
c.
f(x) = 6x – 4
d.
f(x) = –4x – 4

Is this a polynomial function? i need to know asap

Calculate the missing value. round the answer to on decimal place. start with 70, increase it by 21%, and end up with

(05.03 mc) part a: explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of the equation 4x = 2x−2. (4 points) part b: make tables to find the solution to 4x = 2x−2. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 4x = 2x−2 graphically? (2 points)
