Find the equation in standard form of the parabola whose vertex is at the origin and contains the point (1, 6).

The equation in standard form is [tex]\( y = ax^2 \)[/tex].

To determine [tex]\( a \)[/tex], substitute the point (1, 6):

[tex]\[ 6 = a(1)^2 \][/tex]

So, [tex]\( a = 6 \)[/tex].

Thus, the equation in standard form is:

[tex]\[ y = 6x^2 \][/tex]



Answer :

To find the equation of a parabola with a vertex at the origin and passing through the point (1, 6), follow these steps:

1. Understand the Standard Form of a Parabola:
The standard form of a parabola with the vertex at the origin is given by:
[tex]\[ y = ax^2 + bx + c \][/tex]
Since the vertex is at the origin (0, 0), this simplifies further:
[tex]\[ y = ax^2 + bx \][/tex]
Because the vertex is at (0, 0), both [tex]\(b\)[/tex] and [tex]\(c\)[/tex] are zero:
[tex]\[ y = ax^2 \][/tex]

2. Substitute the Given Point into the Equation:
You know the parabola passes through the point (1, 6). Substitute [tex]\(x = 1\)[/tex] and [tex]\(y = 6\)[/tex] into the simplified equation [tex]\(y = ax^2\)[/tex]:
[tex]\[ 6 = a(1)^2 \][/tex]
Simplifying this:
[tex]\[ 6 = a \][/tex]

3. Plug [tex]\(a\)[/tex] Back into the Standard Form:
Now that you have [tex]\(a = 6\)[/tex], substitute this value back into the equation [tex]\(y = ax^2\)[/tex]:
[tex]\[ y = 6x^2 \][/tex]

4. Determine the Coefficients:
From the equation above, we see that:
[tex]\[ a = 6, \quad b = 0, \quad c = 0 \][/tex]

Therefore, the equation of the parabola in standard form is:
[tex]\[ y = 6x^2 + 0x + 0 \][/tex]

So to write it neatly, the standard form of the equation is:
[tex]\[ y = 6x^2 \][/tex]
This is the equation of the parabola whose vertex is at the origin and which passes through the point (1, 6).
