Use the parabola tool to graph the quadratic function. f(x)=(x−1)2−4

See explanation

Step-by-step explanation:

The quadratic function f(x) is defined by its equation

From this equation, you can see such things:

So, you can plot the graph of this parabola (see attached diagram)

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
