Consider the function f(x) = x2 + 2x – 15. What are the x-intercepts of the function?


Sagot :

Step-by-step explanation:

X intercept, y = 0

x² + 2x - 15 = 0

x² + 5x - 3x - 15 = 0

x(x + 5) - 3(x + 5) = 0

(x + 5)(x - 3) = 0

x = -5 and x = 3

X - Intercept = (-5 , 0) and (3 , 0)

Answer:

Step-by-step explanation:

x^2 + 2x - 15 = 0

(x - 3)(x + 5) = 0

x = 3 or x = -5

left-most x-intercept: (-5, 0)

right-most x-intercept: (3, 0)
