Which statement is true about the function represented by this graph?

Choice D)

The function has a range of all real numbers less than or equal to 2.

=======================================================

Explanation:

Let's go through the answer choices to see which are true, and which are false.

A) This is false because (0,-2) is a y intercept, and not an x intercept. A zero of a function is always an x intercept.B) This is false. The curve peaks at the vertex (2,2) showing we have a max point, and not a min point.C) This is false. A function can have at most one y intercept. If it had more than one y intercept, then it wouldn't be a function (since the input x = 0 leads to more than one output).D) This is true. The range is the set of possible y outputs. We see that y = 2 is the largest output, which occurs at the vertex. We can get anything smaller than this y value. Therefore, the range is the set of y values such that

the first step is adding 40 to both sides of the equation

Step-by-step explanation:

Solving the quadratic equation means we solve the equation for x

To solve for x we need to isolate x^2

To isolate x^2, remove -40 from the left hand side

In order to remove -40 we do opposite operation

Opposite of -4 is +40

So we add 40 on both sides of the equation

the first step is adding 40 to both sides of the equation
