Step-by-step explanation:
multiply it
x²-3x+3x-9=0
x²-9=0
x²=9
square root both side we get
x=3
Answer:
The given statement that value 5 is an upper bound for the zeros of the function f(x) = x⁴ + x³ - 11x² - 9x + 18 will be true.
Step-by-step explanation:
Given
We know the rational zeros theorem such as:
if 
is a zero of the function 
,
then 
.
As the is a polynomial of degree 
, hence it can not have more than real zeros.
Let us put certain values in the function,
, 
, 
, 
,
, 
, 
, 
, 
From the above calculation results, we determined that zeros as
and 
.
Hence, we can check that
Observe that,
, increases rapidly, so there will be no zeros for 
.
Therefore, the given statement that value 5 is an upper bound for the zeros of the function f(x) = x⁴ + x³ - 11x² - 9x + 18 will be true.
Answer:
Step-by-step explanation:
Tax
Meal plus tax = 25.3 + 8/100 * 25.3
Meal plus tax = 25.3 + 2.024 Round later. Find the total.
Meal plus tax = 27.324
Meal plus tax = 27.32 rounded to the nearest cent.
Tip
Total cost = 27.324 + 27.324 * 18 /100
Total cost = 4.91832 + 27.324
Total cost = 32.242
Rounded to nearest cent = 32.24 You should always round at the last step.
X^2 - 3x + 2 =
(x - 1)(x - 2) <==
Answer:
The x-intercept is the location on the graph when the output is 0.
f(x) > 0 is intervals of the domain where the graph is above the x-axis.
y-intercept is the location on the graph when the input is 0.
f(x) < 0 is intervals of the domain where the graph is below the x-axis.
