You can plug them each of them into a graphing calculator into y= and then check the table and compare which one is correct. Hope this helps
Answer:
amplitude=5
Step-by-step explanation:
y=a sin x
amplitude =|a|
here a=-5
|a|=5
<span> f(x) = x^2 + 4x − 1 and g(x) = 5x − 7
</span>(fg)(x) = (x^2 + 4x − 1)(5x − 7)
(fg)(x) = 5x^3 + 20x^2 - 5x - 7x^2 - 28x + 7
(fg)(x) = 5x^3 + 13x^2 - 33x + 7
answer is C. third choice
(fg)(x) = 5x^3 + 13x^2 - 33x + 7
Answer:
X = 9, -1
Step-by-step explanation:
1, Factor it
(x-9) (x+1) = 0
2. Both of a factor will = 0
x-9 = 0
x+1=0
3. Solve
x=9
x=1
You would do 1/4 and get the answer plus 3/8s answer
