Answer:
+1 and -1
Step-by-step explanation:
The function in this problem is:
First of all, we have to define the domain of the function, which is the set of values of x for which the function is defined.
In order to find the domain, we have to require that the denominator is different from zero, so
which means:
So the domain is all values of x, except from 4 and -7.
Now we can solve the problem and find the zeros of the function. The zeros can be found by requiring that the numerator is equal to zero, so:
This is verified if either one of the two factors is equal to zero, therefore:
and
We see that both values are part of the domain, so they are acceptable values: so the zeros of the function are +1 and -1.
Answer:
-2.2 (-2.2124%) is the answer as -2.2124^2 = -4.89% is found first below. -2.2124 is part of the derivation equation to find the relation with z.
z<-1.05 therefore = -2.2<-1.05
Step-by-step explanation:
-4.89%
-0.27631578947 x 74= -20.4473684208
P)z<-105) = 100/-20.4473684208 = -4.89060489067 less than the population of 100%
0 = population standard deviation = 3.8 we divide from 1.05
(in normal derivation questions we can multiply before dividing 0 key letter =(z- u)^2 / divide all by N) This is why we divided.
N = the size of the population = 100/D we used 100/D to find the first part.
z = each value from the population = z<-1.05
u = the population mean = 74 we multiplied second step after first step 3.8 we divide from 1.05
So that 1.05/3.8 = -0.27631578947 x 74 = D
We then Divide into N = 100/D
to find a whole or a percentage.
= -4.89
z = -2.2
The linear function is popular in economics. It is attractive because it is simple and easy to handle mathematically. It has many important applications.
Linear functions are those whose graph is a straight line.
A linear function has the following form
y = f(x) = a + bx
A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.
a is the constant term or the y intercept. It is the value of the dependent variable when x = 0.
b is the coefficient of the independent variable. It is also known as the slope and gives the rate of change of the dependent variable.
Graphing a linear function
To graph a linear function:
1. Find 2 points which satisfy the equation
2. Plot them
3. Connect the points with a straight line
