Question

Write the equation of the graphs below and explain

Answer 1

Answer:

  y = 3√(x+3) -2

Step-by-step explanation:

The given points seem to match those of (half) a parabola that opens to the right. The parent function would be ...

  x = y^2

or ...

  y = √x . . . . . gives the upper half of the parabola only

It seems to have a vertical expansion by a factor of 3 and a translation of the vertex from (0, 0) to (-3, -2). The transformed function is then ...

  y = 3√(x +3) -2

_____

We have transformed the parent function using ...

  y = a·f(x-h) +k

where a is the vertical expansion factor, h is the horizontal translation, and k is the vertical translation.
