Answer:
We are asked to find which graph represents the graph of the piecewise-defined function g(x) given as:
g(x)= x^2-4 ; if x < -1
1 ; if -1≤ x ≤ 1
and x^2+4 ; if x>1
i.e. in the region (-∞,-1) we will get a graph of a quadratic function x^2-4.
in the region [-1,1] we will get a straight line y=1.
and the region (1,∞) again we will get a graph of a quadratic function x^2+4.
Also the graph of the function is discontinuous at 1 and -1.
since the limit of the function at x=-1 and at x=1 does not exist.
As at x=-1.
Left hand limit= -3 (x^2-4; at x=-1 gives -3)
and right hand limit =1.
Whereas at x=1.
left hand limit=1
and right hand limit=5 ( x^2+4=1+4 )
Answer:you do length times width times height to get your answer.
Step-by-step explanation: do 12 x 6 x 5 to equal 360
Answer:
b=1
Step-by-step explanation:
-11+3(b+5)=7
-11+3b+15=7
-11+15+3b=7
4+3b=7
3b=7-4
3b=3
3b/3=3/3
b=1

-1 is less than 0, so you use the first equation:
3(-1) +2 = -3+2 = -1
f(-1) = -1
For 0 use the 2nd equation:
3(0) + 4 = 0+4 = 4
f(0) = 4
For 2 use the 2nd equation:
3(2) + 4 = 6+4 = 10
f(2) = 10
1/2x+y=-6 y=3/5x+5
substitute
1/2x+3/5x+5=-6
11/10x+5=-6
11/10x=-11
11x=-110
x=-10
