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
The solution of the given equation by rounding off it to the nearest ten-thousandth is 55.5000.
What is a round-off of the digit?
In mathematics, a round-off is defined as an approximation of the given number to a fewer number of significant digits by taking into consideration some rules.
For eg: 13.58 ~ 13.6
Solving the given equation: 8 x = 444
We are given that 8 x = 444 —- 1
x = 444 / 8
= 55.5
Hence, the solution of the given equation rounded off to the nearest ten-thousandth is 55.5000.

Answer:
Graph A is a function, and Graph B is not
Step-by-step explanation:
A function is when each x-value (aka input) has 1 corresponding y-value (or output).
We see that graph 1 is linear, and that each x-value has it's own y-value, and not multiple y-values.
However, Graph B curves, making it so some of the x-values have more than 1 y-value.
D = 15(t + 1)
Explanation:
It would be t + 1 rather than t - 1 because he has one *more* hour compared to the other riders.
The reason why t + 1 is in parentheses is because when solving, you'd have to first add instead of multiply.
