Answer:

g(x) = -∛(x-7)

Step-by-step explanation:

Reflection in the y-axis changes the sign of x, so after this transformation, the function is ...

g(x) = f(-x)

Then, translation 7 units to the right replaces x by (x-7), so after both transformations, the function is ...

g(x) = f(-(x -7)) = f(-(x -7))

Using the given definition for f(x), we have ...

$g(x)=\sqrt[3]{-(x-7)}\\\\g(x)=-\sqrt[3]{x-7}$

Use the parabola tool to graph the quadratic function f(x)=−5x2−2.

alexira [117]

$\text{Consider the quadratic function}\\
\\
f(x)=-5x^2-2\\
\\
\text{For a quadratic equation, }f(x)=ax^2+bx+c, \text{ we know that the x-coordinate}\\
\text{of the vertex (h,k) is given by}\\
\\
h=\frac{-b}{2a}\\
\\
\text{on comparing the given equation with standard equation, we have}$

$a=-5, b=0, c=-2\\
\\
\text{so the x-coordinate of the vertex is }\\
\\
h=-\frac{b}{2a}=-\frac{0}{2(-5)}=0\\
\\
\text{so plug this vlaue of the h in the given function to get the y-coordinate}\\
\text{of the vertex. so}\\
\\
f(x)=-5(0)^2-2=0-2=-2\\
\\
\text{hence the vertex of the parabola is: }(h,k)=(0,\ -2)\\
\\
\text{A second point on the graph can be found by putting x=1, so }\\
\\
f(1)=-5(1)^2-2=-5-2=-7\\
\\
\text{so one other point on the parabola is }(1,-7)$

The grpah of the quadratic function is shown below:
