Q:

A polynomial function can be written as (x - 1)(x - 4)(x + 7). What are the x-intercepts of the graph of this function?a.(1,0). (4,0), (7,0)b.(-1,0).(-4,0), (-7,0)c.(1,0), (4,0), (-7,0)d.(-1,0), (-4,0), (7,0)​

Accepted Solution

A:
X - intercepts are also known as zeros. To solve this simply take each factor of the polynomial and set it equal to zero. Solve for x then you'll have your x - value of the x intercept.x - 1 = 0x - 1 +1 = 0 + 1x = 1x - 4 = 0x - 4 + 4 =0 +4x = 4x + 7 = 0x + 7 - 7 = 0 - 7x = -7 ^^^All the above are the x values of the x - interceptsThe answer is...C. (1 , 0) (4, 0) ( -7, 0) Hope this helped!~Just a girl in love with Shawn Mendes
