The correct answer is Choice B. The graph is symmetrical about the y-axis.

The quadratic parent function is a parabola. It is shaped like the letter U. Therefore, you could draw a vertical line (y-axis) down the middle and it would be symmetrical.

The correct answer is B) its graph is symmetrical about the y-axis.

It is not symmetrical about the x-axis; you cannot "fold" the graph across the x-axis.
Its domain is not the set of non-negative numbers; you can use negative numbers for x as well as positive.
Its range is not the set of all real numbers; we cannot get a negative y-value from squaring a number.

Given the problem below what mistake did Bob make in solving the equation? Bob and his friends paid $30 for 3 sandwiches and and

storchak [24]

Answer:

Bob forgot to distribute 3 to 1.50 in the parentheses

Step-by-step explanation:

Bob made the mistake in his first step.

In the equation 3(x + 1.50) = 30, the 3 has to be distributed to both x and 1.50.

But, Bob only distributed it to x, which led him to get the wrong answer.

So, Bob's mistake when solving was that he forgot to distribute the 3 to 1.50
