-8x+ 4y= -16
4y= 8x - 16
divide it by 4
y= 2x -4
if x is 0 what is y?
y = 2 (0)-4
y = 4
just put an x value in the equation u will get your y value
1 (0,4)
2 (1,-2)
3 (2,0)
4 (3,2)
5 (4,4)
Answer:
k = -2
Step-by-step explanation:
14+4k = 2-2k
4k+2k = 2-14
6k = -12
k = -12/6
k = -2
it’s not an exponential function because it is a quadratic function
an exponential function is y=2^x
Answer: Choice B. The degree of the function is even, so the ends of the graph continue in the same direction. Because the leading coefficient is negative, the left side of the graph continues down the coordinate plane and the right side also continues downward.
That's a long winded way of saying "both ends go down together". That's how I think about it anyway.
The degree of the polynomial is the largest exponent, which in this case is 4. This is an even number so the ends either go up together or go down together. The leading coefficient being negative (specifically -1) indicates the ends go down together. I recommend looking at a graph or a table of values to see why this is the answer.
