Y=x^2 is reflected in the x axis and then scaled vertically by a factor of 1÷8

The given curve is → x²=y, which is a parabola opening upwards and vertex at (0,0).

When it is reflected in x axis ,the curve becomes→ x²=-y

The graph of two curves are shown.

Now the curve ,x²= -y is scaled vertically by a factor of 1/8.

So, the equation of curve becomes ,→ x²= -y × 1/8

 → x² = -y/8

Plotting the graph of  →x² = -y/8

The curve will shrink, as scaling is less than 1.

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
