The parabola y=x^2 is reflected across the x axis and then scaled vertically by a factor of 1/8.

tekilochka [14]

ANSWER

The new equation is:

$y = - \frac{1}{8} {x}^{2}$

EXPLANATION

The given parabola has equation,

$y = {x}^{2}$

This is the parent function.

When we reflect this parabola in the x-axis and then scaled vertically by a factor of 1/8.

The new equation becomes:

$y = - \frac{1}{8} {x}^{2}$

If y = 3x+b intersects y= mx +3 at (2, 3), find the value of b and m.

Darina [25.2K]

Answer:

The value of b is -3 and m is 0.

Step-by-step explanation:

You have to substitute the coordinates into both equation in order to find m and b value :

Find m,

$y = mx + 3$

At (2,3),

$3 = m(2) + 3$

$3 - 3 = 2m$

$2m = 0$

$m = 0$

Find b,

$y = 3x + b$

At (2,3),

$3 = 3(2) + b$

$b + 6 = 3$

$b = 3 - 6$

$b = - 3$
