Answer:
y = -3cosx
Step-by-step explanation:
Let me rewrite your question:
- One x-intercept is ( pi/2 , 0) so we know that it is a trigonometric function such as cosine that has x-intercept (pi/2,0).
-
The maximum value is 3, it means the amplitude must be 3: y = 3 cos x
-
The y-intercept is (0,-3), means when x =0, y will equal to negative 3 (-3) then it is the function y = -3cosx,
So y = -3cosx is the function has the given properties
Answer:
f - 65 pages per hour
Step-by-step explanation:
420 - 160 = 260
6 - 2 = 4
260 divided by 4 is 65 on average per hour
Answer: "If there are not seven days in a week, then Halloween is not on October 31st.", and it is false because the inverse of a true conditional statement is false. Hope this helps and have a great day!
Answer:
Neither Even nor Odd
Step-by-step explanation:
We are given that
Hence f(-1) ≠ f(1)
And neither f(-1)=-f(1) nor f(-1)=f(1)
Hence it is neither an even function nor an odd function
The correct answer is
The explicit formula is of the form
,
where a₁ is the first term and r is the common ratio. Comparing this to our explicit form, we see that r = -4 and a₁ = 7.
The recursive formula is of the form
; using r=-4 gives us
