3(2+x)
3x2=6
3 x X =3x
So 3x+6
Answer:
See the explanations below
Step-by-step explanation:
Given the function y = x²+12x
We are to find the inverse and identify the error in the calculation:
Step 1: Replace y with x
x = y²+12y
First Error: There is an error here y, the variable attached to x should be y and not x that is y = y²+12y and not y = y²+12x. The x should be totally replaced with
The second error is where he wrote y = √-11x
The square root of a value must return both negative and positive value not only the positive value. Hence the correct expression should have been y = ±√-11x (Note that the sign ± was introduced)
Third error: Since the value inside the square rot is a negative value hence the value of x must be negative i.e x must be less than zero not greater then. The correct inequality expression should have been <u>x <0</u> and not
x< 0
The parent function of
is
The diagrams below show step by step transformation
As we can see from the graph
, the amplitude of the function is 3, period of
, phase shift of π and midline y=2
Answer:
In April 153 millimeters of rain fell on the banana farm.
Step-by-step explanation:
Given:
Farm received rain in March and April = 271 millimeters
Farm received rain in March = 118 millimeters.
We need to find rain received by farm in April.
It can be calculated by Subtracting rain received by farm in march with total rain received by farm in March and April with
Rain fell in farm in April = Farm received rain in March and April - Farm received rain in March = 271 -118 = 153 millimeters.
Hence Banana Farm received rain of 153 millimeters in April.
