Q:
# f(x)= x^2 -16x+63 find the x-intercepts of this function

Accepted Solution

A:

Answer:The x-intercepts will be, x= 7 or x =9Step-by-step explanation:f(x)= x^2 -16x+63 At the x-intercept, f(x) is zero. Therefore;x² - 16x + 63 = 0solving it quadratically;product = 63 Sum = -16 x² - 9x - 7x + 63 = 0x(x-9) - 7( x-9) = 0(x-7) (x-9) = 0x = 7 or x = 9Therefore; The x-intercepts will be, x= 7 or x =9
