Answer:
Answer is below
Step-by-step explanation:
Evaluate for x=6,y=11
So therefore your answer is 115
Answer:
Step-by-step explanation:
We want to simplify;
We expand the bracket to obtain;
We now group the like terms to obtain;
We now simplify to get;
The correct answer is C
166.7x3= 500.1 this is the answer
26 is probably the answer
Axis of symmetry = x = -b/2a
where y = ax² + bx + c
f(x) = x² + 6x - 1 ⇒ a = 1 ; b = 6 ; c = -1
x = -(6)/2(1) = -6/2 = -3
g(x) = -x² + 2 ⇒ a = -1 ; b = 0 ; c = 2
x = -0/2(-1) = 0/-2 = 0
h(x) = 2x² - 4x + 3 ⇒ a = 2 ; b = -4 ; c = 3
x = -(-4)/2(2) = 4/4 = 1
least : f(x) = x² + 6x - 1 ; axis of symmetry is -3
middle : g(x) = -x² + 2 ; axis of symmetry is 0
greatest : h(x) = 2x² - 4x + 3 ; axis of symmetry is 1
