The graph of a certain quadratic function has no x-intercepts. Which of following are possible values for the discriminant? Check all that apply. \( \square \) A. -18 \( \square \) B. 0 \( \square \) C. -4 \( \square \) D. 25

tinh \( a x^{2}+2 x+3 y=6 \)

(b) \( \frac{3}{x-1}<\frac{2}{x} \)

1) \( \frac{10 x+8}{3 a-b}-\frac{9 x+5}{3 a-b}= \)

In the \( x y \)-plane, a parabola has vertex \( (9,-14) \) and intersects the \( x \)-axis at two points. If the equation of the parabola is written in the form \( y=a x^{2}+b x+c \) where \( a, b \), and \( c \) are constants, which of the following could be the value of \( a+b+c \) ? (A) -23 (B) -19 (D) -12

Subtract the polynomials: \( (5x^{3} + 2x^{2} - 7) - (3x^{3} - x^{2} + 4) \)
