How do you interpret domain and range

The domain is the set of feasible input for the function. For example, functions with denominator can't have a zero denominator, logarithm can't have zero or negative inputs, and even roots can't have negative inputs.

Visually speaking, the domain is a subset of the x axis (or possibly the whole axis), so the domain gives you an idea how "how far the function goes", horizontally.

The range is the set of all possible outputs of your function, depending on all possible inputs.

Visually speaking, the range is a subset of the y axis (or possibly the whole axis), so the range gives you an idea how "how far the function goes", vertically.

Answer:

$m = \frac{1}{2}$

Step-by-step explanation:

$\frac{y2 - y1}{x2 - x1}$

$\frac{2-1}{3-1}$

$2-1 = 1\\ 3-1=2$

$m = \frac{1}{2}$

F(x) = 1 / 2<br> g(x) = x - 4<br> Can you evaluate (g o f) (0)? Explain why or why<br> not.

Vitek1552 [10]

For this case we have the following functions:

$f (x) = \frac {1} {2}\\g (x) = x-4$

We must find $(g_ {o} f) (x)$ . For definition of composition of functions we have to:

$(g_ {o} f) (x) = g (f (x))$

So:

$g (f (x)) = \frac {1} {2} -4 = \frac {1-8} {4} = \frac {-7} {4} = - \frac {7} {4}$

Then, for any value of "x", the composite function has a value of $- \frac {7} {4}$ .

Thus, $(g_ {o} f) (0)$ cannot be evaluated, it will always be obtained $- \frac {7} {4}.$

ANswer:

For any value of "x", the composite function has a value of $- \frac {7} {4}.$

Answer:

270

Step-by-step explanation:

The formula for finding the area of a triangle is <em>base · height ÷ 2, </em>or $\frac{bh}{2}$

After plugging in the numbers given to the formula, we find that the area of the triangle is 27.

Then to account for the length, we multiply the area of the triangle by 10.

This gets us to 270.

(11x - 1)<br> (20x – 3)<br> 151°

IgorC [24]

Answer:

x= 1.6 degrees

Step-by-step explanation:

to find the missing angle 180 degrees - 151 degrees

29° is the missing angle at the bottom ryt of the triangle.

all angles in triangle add upto 180°

so, 20x-3°+11x-1°+29°= 180°

31x=180°-25°

x= 1.6°
