What is the input value for which g(x)=3? x=

Mathematics
1 answer:
Mandarinka [93]3 years ago
4 0

Answer:

x =9

Step-by-step explanation:

We want the value when g(x) = 3

We want when the y = value is 3

When y = 3 the x value is 9

g(9) =3

Robin randomly selects a number between 1 and 20 what is the probabilty that the number selected is the square of a natural numb
Ket [755]
Squares of Natural numbers from the range of 1 to 20:
1^2 = 1
2^2 = 4
3^2 = 9
4^2 = 16
(whereas 5^2 = 25 which is outside the range).

There are 4 numbers out of 20, so the probability is 4/20*100% = 20%

The graph of F(x), shown below, has the same shape as the graph of
timama [110]
If g(x) = -f(x), then the graph of g is obtained from the graph of f by reflecting about the x-axis. Suppose, for example, that f(2) = 3, so the point (2,3) is on the graph of f. Since g(x) = -f(x), then g(2) = -f(2) = -3, and the point (2,-3) is on the graph of g.

if a point on the graph of a proportional relationship is located at 3,4, can you determine the constant of proportionality? exp
Mashutka [201]

The answer is: No, because we also need to know the type of proportionality


In mathematics, we talk about proportionality when two variables are related and this relationship is that there is a constant ratio between them. There are two types of proportionality.


1. Direct Proportionality:

If there are two variables x and y, we can write the relationship between them as follows:


y=kx


So, by substituting the point in this equation we have that the constant of proportionality is:


4=k(3) \\ \\ \therefore \boxed{k=\frac{4}{3}}


2. Inverse Proportionality:


In this case, the relationship is:


y=\frac{k}{x}


So, the constant of proportionality is:


4=\frac{k}{3} \\ \\ \therefore \boxed{k=12}


As you can see, we have found two different values of the constant of proportionality. So, it is necessary to know the type of proportionality.
