To be a function every x should have only one y-value.
<span>a. (0,0), (1,1), (2,2), (3,3), (4,4) - We do not see repeating values of x, so it is a function
</span>b. (0,8), (1,6), (2,4), (3,2), (4,0)- We do not see repeating values of x, so it is a function
<span>c. (3,0), (3,1), (3,2), (3,3), (3,4) - We see repeating value of x, that means that one value of x corresponds many values of y , so it is not a function.</span>
Answer:
Larry is wrong
Step-by-step explanation:
Multiplying big numbers will give significantly bigger results then multiplying smaller numbers then adding them. 14 + 12 = 26 & 8 + 12 = 20. 14 x 12 = 68 & 8 x 12 = 96. 96 + 168 is alot less then 26 * 20 so that is why larry is wrong
Answer:
75 of them are red
Step-by-step explanation:
Answer:

Step-by-step explanation:
The y-intercept (when x = 0) on the quadratic graph is 3, the upper quadratic graph does not intersect the x-axis, and the endpoint of the function has an open circle that stops at x = 1. The starting point extends to the boundaries of the graph
Therefore, the piecewise function shown in the quadratic graph is given as follows;
f(x) = x² + 3; x < 1
The straight line graph has a negative slope and starts at x = 1, with a closed circle, extending to higher values of <em>x</em> to the boundaries of the graph
Two points on the straight line graph are (1, 3) and (5, -5), therefore, the slope is (-5 - 3)/(5 - 1) = -2
The equation of the function is y - 3 = -2·(x - 1)
∴ y = f(x) -2·x + 2 + 3 = -2·x + 5
f(x) = -2·x + 5; x ≥ 1
Answer:
Oceans and the Sun.
Step-by-step explanation:
Lakes and the sun is also a good answer, but the question is asking which interact the <em>most</em>, which is the ocean and sun.
We can also rule out the moon since it has nothing to do with the water cycle, so the last two options are also wrong.
