Answer:
(-1,-9/2)(0,-4)(1,-7/2)(2,-3)
Step-by-step explanation:
In fact you just need to do the calcuolation step
when x= -1,y=1/2 *-1 -4=-9/2
when x=0 y=1/2*0-4= -4
when x=1 y=1/2*1-4=-7/2
when x=2 y-1/2 *2-4=-3
Answer:
y = 2(x-2)^2+5
Step-by-step explanation:
Vertex form is y - h = a ( x - k ) ^ 2, where (h,k) is the vertex.
the vertex of the quadratic function is (2,5)
Plug the numbers into the equation which gives you y - 5 = a( x-2)^2
Bring over the five and you have y = a(x-2)^2 +5
That narrows down your options to two answers. The graph opens upward, so the value of a is positive. That leaves one option y = 2(x-2)^2+5.

Answer:
I Couldn't find a variable to solve for. This equation is invalid, the left and right sides are not equal, therefore there is no solution.
Step-by-step explanation:
Simplify
-4 + 2x = 5 + -1(x + -3) + 3x
Reorder your terms
-4 + 2x = 5 + -1(-3 + x) + 3x
-4 + 2x = 5 + (-3 * -1 + x * -1) + 3x
-4 + 2x = 5 + (3 + -1x) + 3x
Combine your like terms 5 + 3 = 8
-4 + 2x = 8 + -1x + 3x
Combineyour like terms -1x + 3x = 2x
-4 + 2x = 8 + 2x
Add -2x to each side of your equation.
-4 + 2x + -2x = 8 + 2x + -2x
Combine your like terms: 2x + -2x = 0
-4 + 0 = 8 + 2x + -2x
-4 = 8 + 2x + -2x
Combine your like terms: 2x + -2x = 0
-4 = 8 + 0
-4 = 8
Solving
-4 = 8
I'm sorry but I Couldn't find a variable to solve for. This equation is invalid, the left and right sides are not equal, therefore there is no solution.
