What is the range of f(x)?

Alex Ar [27]

Answer:

$\{f(x)\ |\ -\infty$

Step-by-step explanation:

The range of the function are all possible values of f(x).

From the diagram you can see that

for all $x\le 0,$ the value of f(x) is always 4;
for $x\ge 0,$ the value of f(x) decreases from 4.

This means that the range of the function f(x) is

$\{f(x)\ |\ -\infty$

What is the slope of the line with the equation 9x=6+6y

harkovskaia [24]

Given the equation of the line :

$9x=6+6y$

To find the slope convert the given equation to the slope - intercept form

which is like:

$y=m\cdot x+b$

where m is the slope

So, solve the given equation for y:

$undefined$

What kinds of triangles can you use the pythagorean theorem on

saul85 [17]

Answer:

Step-by-step explanation:

The Pythagorean theorem applies to right angled triangles only.

However, for any other triangle, by dropping a perpendicular from any vertex on to the opposite side, you form two right angled triangles both of which can be solved by the Pythagorean theorem.

So, the Pythagorean theorem applies to right angled triangles directly and to other triangles indirectly.

A father’s age is the square of his son’s age (x). In 20 years’ time the father will be 3 times as old as his son. What are the

VMariaS [17]

If the current son's age is x, the current age of the father is $x^2$ .

In 20 years they will be, respectively, $x+20$ and $x^2+20$ years old, and we know that the father will be 3 times as old as his son:

$x^2+20=3(x+20) \iff x^2+20=3x+60 \iff x^2-3x-40=0$

The quadratic equation has solutions

$x_{1,2}=\dfrac{3\pm\sqrt{9+160}}{2}=\dfrac{3\pm 13}{2}$

So, the two solutions are

$x_1 = \dfrac{16}{2}=8,\quad x_2 = \dfrac{-10}{2}=-5$

We clearly can't accept negative values as solution for a problem involving the age of a person, so the only feasible solution is x=8, and we deduce that the father's age is 8 squared, i.e. 64.
