Step-by-step explanation:
<h2>a - b = a + (-b)</h2><h2>a + b = a - (-b)</h2>
for any real numbers
Answer:1
Step-by-step explanation: 1/2 + 1/2 is 1
Based on the graph, all x values are possible so the answer is C.
Answer:
so the vertex is (-4, 0) and the axis of symmetry is x=-4
Step-by-step explanation:
f(x) ≥ -(x+4)^2
f(x) ≥ -(x- -4)^2
this is in the form
f(x)> a(x-h)^2 +k
where (h,k) is the vertex and h is the axis of symmetry
so the vertex is (-4, 0) and the axis of symmetry is x=-4
Quadrants 2 and 4 because in quadrant 2, cosine is negative and sin is positive, while in quadrant 4, cosine is positive and sin is negative
