Consider the function f(x) = ex and the function g(x), which is shown below. How will the graph of g(x) differ from the graph of

SIZIF [17.4K]

Answer: Option C

Step-by-step explanation:

If the graph of the function $g(x)=f(x) +b$ represents the transformations made to the graph of $y= f(x)$ then, by definition:

If $b> 0$ the graph moves vertically upwards.

If $b$ the graph moves vertically down

In this problem we have the function $g(x)=e^x+5$ and our parent function is $f(x) = e^x$

therefore it is true that $b =5 > 0$

Therefore the graph of $f(x)=e^x$ is moves vertically upwards by a factor of 5 units.

The answer is the Option C: "The graph of g(x) is the graph of f(x) shifted up 5 units"

Find the distance (-4,5) and (7,18)

seropon [69]

Answer:

$\sqrt{290}\ units$

Step-by-step explanation:

The distance between points $(x_1,y_1)$ and $(x_2,y_2)$ is

$\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$

Hence, the distance between points $(-4,5)$ and $(7,18)$ is

$\sqrt{(-4-7)^2+(5-18)^2}\\ \\=\sqrt{(-11)^2+(-13)^2}\\ \\=\sqrt{121+169}\\ \\=\sqrt{290}\ units$
