Find the solution of system of equation y= x-4 y=4x+2

Given the equation f(x)=a(b)x where the initial value is 40 and the growth rate is 20% what is f(4)

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (-4, 0) and (6,0). the y-intercept of thefirst parabola is (0, –12). the y-intercept of the second parabola is (0-24). what is the positive difference between the avalues for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth.
