Consider the quadratic function f (x) = x2 - 5x + 6.
What does b = ?

A quadratic function is represented as ax² + bx + c. In this case, if you look at the coefficient of x, you'll see that b = -5.

b is the coefficient of the middle term. In this case, -5

Step-by-step explanation:

In a linear equation, the function is in the form of y=mx+b  

In a linear equation m is the slope. b is a constant, and it is the y-intercept.

f(x) represents the "y" value obtained when a given number is plugged in to x.

In a quadratic equation, (and it would be helpful to insert a carat ^ [shift + 6] before the exponent so it is clear)

the form is  a and b are the coefficients. if none, "1" is understood.

the exponent will determine the shape of the parabola.

The b will determine how far to the left or right the parent graph is transformed. ( divide by 2 and use the opposite sign)

but the c is a constant and still indicates the y-intercept.

the answer is a if my teacher taught me correct
