Answer:

y=-\frac{4}{3}x^{2}

Step-by-step explanation:

The given parabola is a parent function, that is, it's the simplest form of a parabola.

The first transformation is about a reflection across the x-axis, this means that we need to multiplied the squared factor by a negative signed, that is

y=-x^{2}

This represents a parabola reflected across the x-axis.

The second transformation is about a scale factor of 4/3, this means that the function has to be multiplied by this factor to obtain the transformation. The expression would be

y=-\frac{4}{3}x^{2}

Therefore, this final expression represents the function reflected across the x-axis and scaled by a factor of 4/3.

2) At a local grocery store, three bags of peanuts and four bags of almonds cost $27 45.
Scilla [17]

Answer:

$7.60

Step-by-step explanation:

Use a linear function (again)

let x = peanuts

let y = almonds

3x+4y=27.45

5x+2y=24.05

Multiple 2nd equation by 2

3x+4y=27.45

10x+4y= 48.1

7x=20.65

x=2.95

Plug in x into either equation

10x+4y= 48.1

29.5+4y=48.1

4y=18.6

y=4.65

4.65+2.95=7.60
