The answer is 6 because with your use the exponent youll get x^3 + 6x + 9. So the x^2 and the 9 cancel out from bothside and you you are left with kx = 6x. Now divide by x and get k = 6.
y + 2007 = 5/29x
5/29 is the slope and 2007 is the y-intercept
Answer:
Step-by-step explanation:
For a function to have a y-intercept of -1, means that
when x = 0, f(0) = -1.
we must look for which of the options meets this condition.
I will number the options as follows:
when x = 0:
Note: , so
function 1 meets the condition for the y-intercept.
when x = 0
function 2 also meets the condition for the y-intercept.
when x = 0
Note:
function 3 also meets the condition for the y-intercept.
when x = 0
function 4 does not meet the condition for the y-intercept, so we discard it.
We are left with the 3 first functions as options. Now we consiser that the amplited must be 2.
The amplitude in an oscillatory function like these is the number that accompanies the sine or the cosine:
f(x) = ±Asin(x) or
f(x) = ±Acos(x)
so out of the option we have to consider, only the second function has a number 2 next to the sine function:
this function will have a y-intercept of -1 and an amplitude of 2 (because the sine has a number 2 next to it)
Answer:
not sure
Step-by-step explanation:
im not sure where the problem lies so ill just show u what the fuctions mean
for this case it plots out two lines that intercept at the point (4.5 , 4)
i included a pic of the two plotted lines
