The quadratic function, $y=x^{2}$ , has an x-intercept at the origin

From x = -2 to x = 0 , the average rate of change for both functions is negative

For the quadratic function, $y=x^{2}+3$ , the coordinate (2, 7) is a solution to the equation of the function

Step-by-step explanation:

we have the quadratic functions

$y=x^{2}$

$y=x^{2}+3$

Verify each statement

case A) The quadratic function, $y=x^{2}$ , has an x-intercept at the origin

Remember that

The x-intercept is the value of x when the value of y is equal to zero

The point (0,0) represent and x-intercept and a y-intercept

therefore

The statement is True

case B) The quadratic function, $y=x^{2}+3$ , has an x-intercept at the origin

The quadratic function, $y=x^{2}+3$ has no x-intercept

The statement is False

case C) From x = -2 to x = 0 , the average rate of change for both functions is positive

Observing the graph from x = -2 to x = 0 , the average rate of change for both functions is negative

The statement is False

case D) From x = -2 to x = 0 , the average rate of change for both functions is negative

The statement is True

case E) For the quadratic function, $y=x^{2}$ , the coordinate (2, 3) is a solution to the equation of the function

we know that

If a ordered pair is a solution of the quadratic function

then

the ordered pair must be satisfy the quadratic equation

Substitute the value of x and the value of y in the quadratic function and then compare

$3=2^{2}$

3=4 ------> is not true

The ordered pair is not a solution

The statement is False

case F) For the quadratic function, $y=x^{2}+3$ , the coordinate (2, 7) is a solution to the equation of the function

we know that

If a ordered pair is a solution of the quadratic function

then

the ordered pair must be satisfy the quadratic equation

Substitute the value of x and the value of y in the quadratic function and then compare

$7=2^{2}+3$

7=7 ------> is true

The ordered pair is a solution

The statement is True
