Answer:
Step-by-step explanation:
The graph that represents the function
f(x) = (x + 4)(x + 1)(x - 3)
crosses the x-axis three times: at x = -4, x = -1, and x = 3
because we apply the zero product rule and found the roots -4, -1, and 3
x+ 4= 0 → x = -4
x+1 = 0 → x = -1
x-3 = 0 → x = 3
Answer:
The slope-intercept form is
Step-by-step explanation:
To find the slope, use
Replace the x and y values with the points.
Solve.
After that, find the y-intercept form.
Put the equation in point-slope form.
Replace x with 0.
Add 5 to both sides.
Convert to improper fraction form.
The y-intercept is
Now finally, write in slope-intercept form. (y=mx+b)
m is slope, b is the y-intercept.
