Question

what is the value for b
$6x^{2}-4x + 9 = y$
○ -4
○ -9
○ 9
○ 6
question 3
what is the value for c
$x^{2}+9x + 2 = y$
○ -9
○ 9
○ 2

Explanation:

Step1: Recall quadratic standard form

The standard form of a quadratic equation is $y = ax^2 + bx + c$, where $b$ is the coefficient of the $x$-term.

Step2: Identify $b$ in first equation

For $6x^2 - 4x + 9 = y$, the coefficient of $x$ is $-4$.

Step3: Identify $c$ in second equation

For $x^2 + 9x + 2 = y$, $c$ is the constant term, which is $2$.

Answer:

For the first question: -4
For Question 3: 2
