Answer:
(-∞, -4] ∪ [5, ∞)
Step-by-step explanation:
Hi!
Alright, so greater (or less) than or equal to is denoted with a bracket.
If x is less than or equal to -4, then the bracket is on the left side.
(___, -4]
Because x is <em>any</em> number under or equal to -4, x can range from negative infinity. However, we use a parentheses for infinity because infinity can never truly be reached.
So, x 
-4 = (-∞, -4]
X
5
Equal to = bracket
X is any number above 5, so
[5, ∞)
Because we want both of these, we use the union sign (∪)
so,
= (-∞, -4] ∪ [5, ∞)
1) V.A, J.L, C.T, R.R, T.Mc
2) J.L, R.R, C.T, V.A, T.Mc
3) C.T, J.L, R.R, V.A, T.Mc
4) C.T, V.A, T.Mc, J.L, R.R
5) C.T, V.A, J.L, T.Mc, R.R
Given: a quadratic function with vertex (2,3) opening upward .
Find: the given statement is true or false.
Explanation: if parabola has a vertex at (2,3) and opens upward, it has one real solution., (2,3) will be a lowest point. The vertex will be at lowest point, it will be minimum.
that means graph has no one real solution. hence it will never going to intersect. so this statement is false.
Final answer: the given statement is FALSE.
Answer:
x-intercept: (2,0)
y-intercept: (0,-4)
Step-by-step explanation:
x-intercept: when y = 0
2x - 0 = 4
x = 2
y-intercept: when x = 0
2(0) - y = 4
y = -4
