Solve x^2+2=6 by graphing the related function.​

Mathematics
1 answer:
never [62]3 years ago
8 0

Answer: option C.

Step-by-step explanation:

Given  a quadratic function of the form ax^2+bx+c, if the coefficient <em>a</em> is less than zero, then the function is opened upward.

The options A is not opened upwards, then it is not the answer.

Then the given equation x^2+2=6 can be written as:

x^2+2-6=0\\x^2-4=0

This function is equal to the parent function, shifted 4 units down.

Therefore, the graph that you are looking for must be a parabola that is opened upwards and has its vertex in the point (0,-4).

Then, the correct option is C. And the solution is:

x=-2\\x=2

Answer:

C.

discrete data

Step-by-step explanation:

The given function is:

                                                  C(p) = 0.95p

Where p represents the number of bolts purchased. We can calculate the cost based on the number of bolts purchased.

An important distinction between discrete and continuous data is that the continuous data is measured while discrete data is calculated or counted. Since we are obtaining the data by calculation, it must be discrete data.

The function can take on only specific values. For example for p=0, C is 0 and for p=1 the value of C is 0.95. The function cannot take any value in between 0 and 0.95. This is a characteristic of discrete function. A continuous function can take all possible values in an interval.  

Therefore, the answer to this question is: The Function models discrete data.

sammy [17]

The standard compound interest formula is

Future value after x years with an annual interest of i

=Present Value (1+i)^x [which is an exponential function]

for given present value of $360. interest=0.03 (3%) and a total of x years, above equation reduces to

Future value after x years

=360(1.03^x)
