Question 6 • CMS 2026-2027 NC Math 1 CREDIT RECOVERY

Which statement describes the graph of f of x is equal to 4 x squared plus 20 x plus 25 ?

Answer
A
The graph does not intersect the x -axis.
B
The graph touches the x -axis at negative 2 point 5 comma 0 .
C
The graph intersects the x -axis at negative 0 point 4 comma 0 and 0 point 4 comma 0 .
D
The graph intersects the x -axis at 2 comma 0 and 5 comma 0 .

Explanation

Factor the quadratic: 4x² + 20x + 25 = (2x + 5)². Setting it equal to zero gives x = −2.5, a repeated root, so the graph touches the x-axis at (−2.5, 0) rather than crossing it. This matches choice B.
