What is the y-intercept of the quadratic function
f(x) = (x – 6)(x – 2)?

(0,–6)

(0,12)

(–8,0)

(2,0)

The y-intercept is the point (0, 12).

The quadratic function is described by the standard equation

In the equation the value c is the y-intercept of the graph. In other words, the graph passes through the point

We have the quadratic function

Let us configure it to be a standard equation.

Hence, we get

We identify the coefficients a, b, and c. For this equation,

So, the y-intercept of the quadratic function  f(x) = (x – 6)(x – 2) is (0, c), i.e., the point

Note:

Keywords: the y-intercept of the quadratic function, f(x) = (x – 6)(x – 2), the point (0, 12), a standard equation, the x-intercept, the axis of symmetry, the vertex, parabola, upward, downward

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

the first one, all those points on the line just make a strait line.
