Hello,

Line 1 is passing through (-4,3), (-2,7) has a slope of (3-7)/(-4+2)=2

Line 2 is passing through (2,9), (4,1) has a slope of (9-1)/(2-4)=-4

One other way:

y=9-1/2 x²
y'=-x

gradient 1=-(-2)=2 for point (-2,7)

gradient 2=-(4)=-4 for point(4,1)

What is the domain of the function y=^3squareroot of x<br> PLEASE HELP
Ilia_Sergeevich [38]

Answer:

[0,∞)

Step-by-step explanation:

We can easily solve this question by plotting the equation with the use of a plotting tool or any graphing calculator.

The equation is

y=3^(√x)

Please see attached image

Since the x is inside a square root, we know that x must be greater or equal to zero.

By looking at the graph, we can check that the domain of the function is

[0,∞)

Consider the three functions: f(x) = (4)x g(x) = (4)–x h(x) = –(4)x Which statements are true about the domain and range of f(x)
galina1969 [7]
1. Functions of the form f(x)=ax+b, where a is non zero, are called "linear functions" and the graphs of them are inclined lines.

2. If a>0, the line is increasing, so it gets higher as we move x to the right

If a<0, the line is decreasing.

3. There is no x we are not allowed to plug in the function: so Domain = all Real numbers

4. Since the lines are either increasing or decreasing, f(x), represented by the y values, take all values from -∞ to +∞. So Range = all Real numbers.

f(x)=4x  (increasing line, 4>0)      ,
g(x)=-x+4, h(x)=-4x  (decreasing lines, -1<0, -4<0)

all f, g, h have Domain AND Range : All real numbers

If Emily pours 7/9 of a pint of coffee in the cup, how much milk can a customer add to the cup?
svet-max [94.6K]

Answer:  The answer is \dfrac{2}{9}.

Step-by-step explanation: Given in the question that Emily pours \dfrac{7}{9} of a pint of coffee in the cup. We are to find the fraction of the milk that a customer can add to the cup.

Fraction of the pint of coffee in the cup is given by

f_c=\dfrac{7}{9}.

The fraction of the cup that is left unfilled will be

f_u=1-\dfrac{7}{9}=\dfrac{9-7}{9}=\dfrac{2}{9}.

Therefore, the fraction of the cup that can be filled with milk is

f_m=f_u=\dfrac{2}{9}.

Thus, the answer is \dfrac{2}{9}.
