Equation:
----------------------------------------------------------------
y= -4x² + 16x - 7
----------------------------------------------------------------
Find x-intercept:
----------------------------------------------------------------
At x-intercept, y = 0
-4x² + 16x - 7 = 0
(7 - 2x) (2x - 1) = 0
----------------------------------------------------------------
Apply zero product property:
----------------------------------------------------------------
(7 - 2x) = 0 or (2x - 1) = 0
x = 3.5 or x = 0.5
----------------------------------------------------------------
Answer: The x-intercept are (3.5, 0) and (0.5, 0).
