Question

which part of the quadratic equation $y = ax^2 + bx + c$ tells you where the parabola meets the $y$-axis?
a. $b$
b. $x$
c. $c$
d. $a$

Explanation:

Step1: Find y-axis intersection condition

The y-axis is where $x=0$.

Step2: Substitute $x=0$ into equation

Substitute $x=0$ into $y=ax^2+bx+c$:
$y=a(0)^2 + b(0) + c = c$

Step3: Identify the corresponding term

The value $c$ gives the y-intercept, so this is the term that tells where the parabola meets the y-axis.

Answer:

c. c
