No they are not functions
Zigmanuir [339]2 years ago
6 0

Answer:

No it is not a function because the 10 in the input is repeated twice (the arrow is connected to 2 numbers)

D= {7, 9, 10}

R= {7, 9, 8, 10}

The pairs are (7, 7), (9, 9), (10, 8), (10, 10)

I'm having trouble solving this, if anyone could help I'd be most appreciated.
STALIN [3.7K]
You can check that
f(1)=0
f(-3)=0
f(-5)=0

thus:
x^3+7x^2+7x-15=\boxed{(x-1)(x+3)(x+5)}

What does it mean when you need to graph a piecewise function where f(x) =0 if x is not an integer
ruslelena [56]
It means that the graph is discontinuous. It consists of a line that looks like the x axis, but at every integer value of x there will be a hole. The piecewise function will probably contain f(x)=1 or some other function for x equal to an integer. This other function will also be discontinuous because it will consist of isolated points separated by gaps.

Which statement is true about the function f(x) = negative StartRoot x EndRoot?
AleksAgata [21]

It has the same domain but not the same range as the function f(x)=\sqrt{x}

<h2>Explanation:</h2>

The function:

g(x)=-\sqrt{x}

is a reflection over the x-axis of the function:

f(x)=\sqrt{x}

Because every point (x, y) on f(x) is mapped onto (x, -y) on g(x), but the domain of those functions are the same as you can see in the figure below.

f(x) \ is \ the \ blue \ graph \\ \\ g(x) \ is \ the \ red \ graph

However, you can see that:

  • The range of f is [0,\infty)
  • The range of g is (-\infty,0]

So they have different range.

Find the inverse of the following
spin [16.1K]

Answer:

Inverse should be (-2y^2 + 4)/(ln 3)

Step-by-step explanation:

Find Y, for reversed roles/position of X and Y. Cancel out square root with ^2. Cancel out -2 by multiplying. Then, add 4 to both sides to cancel them out. Finally, nature log it and divide it to isolate X.
