A polynomial function can be written as (x + 2)(x + 3)(x β 5). What are the x-intercepts of the graph of this function?
Question
Answer:
(-2,0) (-3,0) (5,0)Make each factor or parentheses equal to zero and solve to get the x value of the intercepts.
x+2 = 0
subtract 2 from both sides
x = -2
x+3 = 0
subtract 3 from both sides
x = -3
x-5 = 0
add 5 to both sides
x = 5
