Question 7 • Algebra II

For what values of m does the graph of y is equal to 3 x squared plus 7 x plus m have two x -intercepts?

Answer
A
m is less than 49 over 12
B
m is greater than 25 thirds
C
m is less than 25 thirds
D
m is greater than 49 over 12

Explanation

A quadratic has two distinct x-intercepts when its discriminant is greater than zero. For y = 3x² + 7x + m, the discriminant is 7² − 4(3)(m) = 49 − 12m. Requiring 49 − 12m > 0 gives m < 49/12, so the correct choice is “m is less than 49 over 12.”
