How do you find the y-intercept(s) of a rational function? -Set the numerator equal to zero
-Set the denominator equal to zero
-Evaluate f(0)
-Set factors that divide out equal to zero

translate k to n and reflect across the line containing jk.

step-by-step explanation:

the answer is 128

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
