First function value f(x) is increasing as x is increasing. Also the slope of this first function is not fixed. its y-intercept is also not listed in the table as there is not value given when x=0.
Second function g(x) is falling to the right. so it has a negative slope. from the graph, the line is cutting y-axis at -3, so its y intercept is -3. since it has fell 4 units when moving right by 1 unit, its slope must be -4. so its equation may look like \(g(x) = -4x-3\)
The third function is falling because of its negative slope(-4), since c = 3, it cuts y axis at 3 which is the y intercept.
Fourth function is increasing because it says Cameron is adding things to his collection. since he started wid 3 toys, y intercept is 3. since he adds 4 toys to his collection every year, slope = 4. so the equation for fourth function is \(j(x) = 4x+3\)
