Equation:
----------------------------------------------------------------
 y= -4x² <span>+ 16x - 7

</span>----------------------------------------------------------------
<span>Find x-intercept:
</span>----------------------------------------------------------------<span>
At x-intercept, y = 0

</span> -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).
