Answer:

option #1 is a reflection over the x-axis.

Step-by-step explanation:

option #1 is a reflection over the horizontal axis, which is the x-axis. the end of the bold horizontal line in the middle of the graph (the one that goes from side to side) is labeled with an "x" which indicates that it's the x-axis.

option #2 is a reflection over the vertical axis, which is the y-axis. the top of the bold vertical line in the middle of the graph (the one that goes up and down) is labeled with a "y" which indicates that it's the y-axis.

option #3 is not a reflection over either of the axes. it actually seems to be a rotation rather than a reflection.

i hope this helps! have a lovely day <3

The table represents an exponential function. A 2-column table has 4 rows. The first column is labeled x with entries 1, 2, 3, 4
scoray [572]

Answer:

The multiplicative rate of change of the function is \dfrac{2}{3}

Step-by-step explanation:

You are given the table

\begin{array}{cc}x&y\\ \\1&6\\2&4\\ \\3&\dfrac{8}{3}\\ \\4&\dfrac{16}{9}\end{array}

An exponential function can be written as

y=a\cdot b^x,

where b is the multiplicative rate of change of the function.

Find a and b. Substitute first two corresponding values of x and y into the function expression:

6=a\cdot b^1\\ \\4=a\cdot b^2

Divide the second equality by the first equality:

\dfrac{4}{6}=\dfrac{a\cdot b^2}{a\cdot b^1}\Rightarrow b=\dfrac{2}{3}

Substitute it into the first equality:

6=a\cdot \dfrac{2}{3}\Rightarrow a=\dfrac{6\cdot 3}{2}=9

So, the function expression is

y=9\cdot \left(\dfrac{2}{3}\right)^x

Check whether remaining two values of x and y suit this expression:

9\cdot \left(\dfrac{2}{3}\right)^3=9\cdot \dfrac{8}{27}=\dfrac{8}{3}\\ \\9\cdot \left(\dfrac{2}{3}\right)^4=9\cdot \dfrac{16}{81}=\dfrac{16}{9}

So, the multiplicative rate of change of the function is \dfrac{2}{3}

If s(x) = 2-x2 and t(x) = 3x, which value is equivalent to (s° f)(-7)?
Anastasy [175]

Answer:

-439

Step-by-step explanation:

Think of the question as s(f(-7))

First replace x with -7 in the equation f(x)= 3x

s(-7) = 3*(-7)

s(-7) = -21

now it is s(-21)

we substitute -21 into the s(x) equation to get 2-(-21)^2

That gives you 2-441 = -439
