Equations and functions

Am I correct? If not which one is the right answer?

second option is correct

Step-by-step explanation:

As we can see, the graph goes up, then stays flat for a while, and then goes up again. The only equation where this is true is the second one, where first the line goes up with the equation f(x)=4x, and then it stays still with the equation f(x) = 5, which will be a straight line, since there is no x value, and then it goes up again with f(x)=2x-1

add a pic of the graph, then ill edit this "answer" and solve it for you : 3

step-by-step explanation:

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
