Question
How does the graph of g(x) = x2 - 4 compare to that of f(x) = x2
The correct answer is: Hence, g(x) is 4 units down from f(x)
Hint:
The vertex form of a quadratic function is
f(x) = a(x – h)2 + k
Where a, h, and k are constants. Here, h represents horizontal translation, a represents vertical translation and (h, k) is the vertex of the parabola. Also, a represents the Vertical stretch/shrink of the parabola and if a is negative, then the graph is reflected over the x-axis.
Solution
The parent function is:
f(x) = x2
In this problem, g(x)= x2 - 4 so if f(x) was shifted 4 units down, the value of f(x) will be
f(x) = x2 - 4 = g(x)
So, g(x) is shifted 4 units down from f(x)
Final Answer:
Hence, g(x) is 4 units down from f(x)

Suppose a goalie kicks a soccer ball. The ball travels in a parabolic path from point (0,0) to (57,0). Consider a quadratic function in vertex form for the path of the ball. Which values can you determine? What values are you unable to determine? Explain.
A polynomial function is referred to as quadratic if it has one or more variables and a variable with a maximum exponent of two. It is sometimes referred to as the polynomial of degree 2 since the greatest degree term in a quadratic function is of the second degree.
The locations whose coordinates are of the form are connected by the parent quadratic function, which has the form f(x) = x2 (number, number2). The parent quadratic function joins the places whose coordinates have the form f(x) = x2 (number, number2). This function, which generally has the form f(x) = a (x - h)2 + k, can be transformed to take the form f(x) = ax2 + bx + c.
