What is f(g(x)) . What does it mean

It means combining functions here is an example -> f (x) = 3x + 2 g(x) = 2x + 7
f (g (x) ) = f (2x + 7 )
= 3( 2x + 7 ) + 2
= 6x + 23
Combining functions is to create a new function that is based off of two or more other functions. You do this with the use of addition, subtraction, multiplication, and division.

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
