Answer:
The quadratic function, [tex]y=x^{2}[/tex], has an x-intercept at the origin
From [tex]x = -2[/tex] to [tex]x = 0[/tex], the average rate of change for both functions is negative
For the quadratic function, [tex]y=x^{2}+3[/tex], the coordinate [tex](2, 7)[/tex] is a solution to the equation of the function
Step-by-step explanation:
we have the quadratic functions
[tex]y=x^{2}[/tex]
[tex]y=x^{2}+3[/tex]
Verify each statement
case A) The quadratic function, [tex]y=x^{2}[/tex], 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 [tex](0,0)[/tex] represent and x-intercept and a y-intercept
therefore
The statement is True
case B) The quadratic function, [tex]y=x^{2}+3[/tex], has an x-intercept at the origin
The quadratic function, [tex]y=x^{2}+3[/tex] has no x-intercept
so
The statement is False
case C) From [tex]x = -2[/tex] to [tex]x = 0[/tex], the average rate of change for both functions is positive
Observing the graph from [tex]x = -2[/tex] to [tex]x = 0[/tex], the average rate of change for both functions is negative
so
The statement is False
case D) From [tex]x = -2[/tex] to [tex]x = 0[/tex], the average rate of change for both functions is negative
The statement is True
case E) For the quadratic function, [tex]y=x^{2}[/tex], the coordinate [tex](2, 3)[/tex] 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
[tex]3=2^{2}[/tex]
[tex]3=4[/tex] ------> is not true
The ordered pair is not a solution
so
The statement is False
case F) For the quadratic function, [tex]y=x^{2}+3[/tex], the coordinate [tex](2, 7)[/tex] 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
[tex]7=2^{2}+3[/tex]
[tex]7=7[/tex] ------> is true
The ordered pair is a solution
so
The statement is True
