In the following quadratic equation identify the values of a, b, and c that you would use in the quadratic formula.
7x^2-3x+9=0
A. a=7 b=-3 c=9
B. a=9 b=7 c=-3
C. a=-7 b=3 c=-9
D. a=7 b=3 c=9

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.

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!

d. 9

step-by-step explanation:

in the table given in the picture, x is the input of the function and f(x) is the output on the given input. in the given table, it can be read as the value of function at -3 is it's respective value of f(x) which is -9.

as we have to find the value of f(3), we will see that what is the value of output on input 3. we can see in the table that the output value at x=3 is 9.

so, option d is the correct answer ..
