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

Answer from: Quest

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
