Additionally, the initial fee is a flat 42 dollars. This is paid once and is unaffected by the number of days we rent. This will be the y-intercept of our function. Now we can write the function in slope-intercept form. y=12x+ 42 Since we want to write this equation using the symbols given in the exercise, we will replace y with the function notation f(x) and place a multiplication symbol between the slope and x. f(x)=12 * x+42
