Can someone me with algebra 2?

a solution of the equation ƒ(x ) = g(x ) is the same as (select all that apply)

the x-value of a solution to the system of equations y = ƒ(x ) and y = g(x ).
the y-value of a solution to the system of equations y = ƒ(x ) and y = g(x ).
the x-coordinate of an intersection point of the graphs of y = ƒ(x ) and y = g(x ).
the y-coordinate of an intersection point of the graphs of y = ƒ(x ) and y = g(x ).

Is it true or false i’m trying to pass this test so i can leave school

The figure below shows rectangle abcd and the triangle eca on a coordinate plane.which of the following expressions represents the perimeter of triangle of triangle eca in units

A. plot the data for the functions f(x) and g(x) on a grid and connect the points. x -2 -1 0 1 2 f(x) 1/9 1/3 1 3 9 x -2 -1 0 1 2 g(x) -4 -2 0 2 4 b. which function could be described as exponential and which as linear? explain. c. if the functions continue with the same pattern, will the function values ever be equal? if so, give estimates for the value of x that will make the function values equals. if not, explain why the function values will never be equal.
