Answer:
A
Step-by-step explanation:
Let's first define what exactly the values of a, b, and c represent.
- a: this is the coefficient of the x^2 term
- b: this is the coefficient of the x term
- c: this is the constant term (no variable attached)
Our equation is: y = 7x^2 - 3x + 9.
The coefficient of x^2 is 7, so a = 7. The coefficient of x is -3, so b = -3. And finally, the constant term is 9, so c = 9.
Thus, the answer is A.
Answer:
The general quadratic equation is ax^2 + bx + c = 0
=> Here, we have: 7x^2 - 3x + 9 = 0 <=> 7x^2 + (-3)x + 9 = 0
=> a = 7, b = -3, c = 9
=> Option A is correct.
Hope this helps!
