Okay so what f(3) is saying is that x=3. You have to plug three in for x to make the new equation of 2(3)^3-3(3)+1 next you would do pemdas which is parethesis then exponets then multiplication/division then addition/subtraction to get 2*3=6 6^3 is 216 216-3*3 is 207 207+1 is 208 so the answer is f(3)=208
Answer:
The answer to your question is: x = - 1 / 8
Step-by-step explanation:
8( 1 - 5x ) = 13
8 - 40x = 13
- 40x = 13 - 8
- 40x = 5
x = - 5 / 40
x = - 1 / 8
Answer: 0.02
Explanation: the absolute value of anything is the distance between the given number and zero.
Answer:
f(x) = 
> f(x) = -0.5x² > f(x) = x²
Step-by-step explanation:
In a quadratic function leading coefficient decides the width of a graph.
In simpler words, leading coefficient decides the vertical stretch of the graph.
Higher the value of leading coefficient, higher the vertical stretch.
When a graph is vertically stretched it becomes narrower.
(Note: Minus sign of the coefficient decides the opening of the graph, upwards or downwards)
Therefore, f(x) = x² having coefficient = 1 is the narrowest and f(x) = will be the widest.
So the descending order will be,
f(x) = > f(x) = -0.5x² > f(x) = x²
Answer:
(6)(3)+(18+6x)
Step-by-step explanation:
6 times 3 will give you the area of the table without the extension and the problem says that (18+6x) is the area for the extension. So when you add up the two areas you get the total area!
