Answer:

Option B is correct.

Explanation:

Given Function is,

y = x² + 4x - 32

X-intercepts of the graph of given function is the solution of the equation when y is equal to 0 is substituted.

y = 0

x² + 4x - 32 = 0

x² + 8x - 4x - 32 = 0

x ( x + 8 ) - 4 ( x + 8 ) = 0

( x + 8 ) ( x - 4 ) = 0

x + 8 = 0 and x - 4 = 0

x = -8 and x = 4

So x-intercept are ( -8 , 0 ) and ( 4 , 0 )

Therefore, Option B is correct.
