Question

How do I solve question 14

Answer 1

The answer to your question is the letter A.

Explanation:

Data

Range from y = 2x²

The Range is the set of values that can be produced by a function.

Process

1.- The function given is a parabola that opens upwards, so we must look for its Vertex.

Formula

y - k = 4p(x - h)

y = 2x²

As we can see there are no "h" or "k".

Then, we conclude that the Vertex is (0, 0).

Conclusion:

The range will be all the numbers higher or equal than 0 (Vertex)

R: y ≥ 0

Answer 2

a R: y≥ 0

Explanation:

The range of the function is the values that y can take

y = 2x^2

The smallest value that x^2 can take is zero

squares are always greater than or equal to zero

so the smallest value y can be is zero

y≥ 0
