f(-1) = -11 and f(3) = -3 . these functions are true .
What does a math function mean?
- A relationship between a group of inputs and one output each is referred to as a function.
- A function is an association between inputs in which each input is connected to precisely one output.
- A domain, codomain, or range exists for every function. f(x), where x is the input, is a common way to refer to a function.
- In mathematics, a function is an expression, rule, or law that establishes the relationship between two variables (the dependent variable).
given function f(x) = 2x - 9
f(-1) = -11 ⇒ x = -1 put in function
f( -1 ) = 2 * -1 - 9 ⇒ - 11
f(2) = 5 ⇒ x = 2 put in function
f( 2 ) = 2 * 5 - 9 = 1
f(3) = -3 ⇒ x = 3 put in function
f ( 3 ) = 2 * 3 - 9 = -3
f(-3) = 15 ⇒ x = -3 put in function
f( -3) = 2 * -3 - 9 = - 15

Answer:
33250
Step-by-step explanation:
Pedro had earned a gross income of 35200 last year.
So, the gross income of Pedro for the current year will also be 35200.
But, this year he has taken the standard deduction of 5450.
Hence, his current year's income will be reduced to (35200-5450)= 29750.
Again, in the current year, he got an exemption of 3500.
Therefore, the net taxable income of Pedro for the current year will become (29750+3500) =33250. (Answer)
B. x > -4 I did da test. That's da correct one :-)
Answer:
x is equal to 4.3
Step-by-step explanation:
since it's -4.3 + x is equal to 0
you take -4.3 to the other side of the equal sign which makes it positive and x is equal to 4.3
