Answer:
4
Explanation:
The amplitude of a sine function is the absolute value of the coefficient of sin(in other words, the absolute value of the number multiplying the sin)
In this case, that is |-4|=4
Answer:
12
Step-by-step explanation:
610 divided by 55 = 11.09
but since u cant have 11.09, u need 12
Answer:
41%. This is because 62/150 equals to 31/75 which, when converted to decimal form, equals to .41333333. That converts to a percent by miving the decimal point 2 to the right and that gives you 41.3333%. That rounds down to 41%.
Step-by-step explanation:
Answer:
Graph C
Step-by-step explanation:
First, we need to find the bottom of the parabola (or the top, left, or right). In this case, it is x=3, therefore meaning y=-25. The only one that has (3,-25), so Graph C.
Answer:
Down.
Step-by-step explanation:
ƒ(x) = 3x³ - x² + 4x - 2
"They" are asking you to determine the end behaviour of the function, that is, what happens to the function as x ⟶ -∞.
The important point to remember is that, when x is large enough, the term of highest degree (the x³ term) will be so large that you can ignore all the other terms.
If x is large and negative,
f(x) ≈ 3(-x)³ = 3(-1)³(x)³= -3x³
Thus, the graph is in the third quadrant and the graph points down.
The figure below shows the graph of your function. It points sharply down on the left-hand side.
