In order to find each of those values, we need to replace x in the appropriate function with the entry given for that function.
Part a
Replace x with 3 in the expression 3x+2:
Part b
Replace x with -2 in the expression 3x+2:
Part c
Replace x with -1 in the expression x²+x+1:
Part d
Replace x with 3 in the expression x²+x+1:
Part e
Replace x with a-2 in the expression 3x+2:
Part f
Replace x with a-2 in the expression x²+x+1:
He has the ability to get it agian after the third pass. He passes it across the circle to Joe, Joe passes to to Bill at his 4 o clock and then Bill can pass it back to the original passer
Answer:
x= 1.5
y= 4.125
Step-by-step explanation:
Step one:
given the two equations
Step two:
let us subtract the equations
divide both sides by 16
put y= 4.125 in equation 2
For the graph in the figure
we know that
the function is a quadratic equation ( vertical parabola) open up
so
The vertex is a minimum
the vertex is the point
The domain x of the function is all real numbers-------> (-∞,∞)
The range is the interval--------> [0,∞)
therefore
Statements

Is false
B) The domain is the set of all real numbers
Is true
C) The domain is the set of all real numbers greater than or equal to zero
Is false
D) The range is the set of all real numbers greater than or equal to zero
Is true
