Answer:
Domain: [0, ∞)
Range: [7850, ∞)
Step-by-step explanation:
A function is defined by the set of ordered pairs having different output values for every input value.
In the graph attached, for every input value (x-coordinates) there is a unique output (y-coordinates) value.
Therefore, graph represents a function.
Domain of the given function → [0, ∞)
Range of the function → [7850, ∞)
Answer:
200
Step-by-step explanation:
<span>y= 2x ^2 - 8x +9
</span>y = a(x - h)2 + k, where (h, k) is the vertex<span> of the parabola
</span>so
y= 2x ^2 - 8x + 9
y= 2x ^2 - 8x + 8 + 1
y = 2(x^2 - 4x - 4) + 1
y = 2(x - 2)^2 + 1 ....<---------<span>vertex form</span>
1. -1
2. 1/2
not sure:
3. 7? —> 7x 1/7x=7x1= 7
4. 1/11?
