Answer:
The second option
x ==> f(x)
-1 ==> 0
0 ==> 3
3 ==> 36
Step-by-step explanation:
Given:
f(x) = 2x² + 5x + 3
{-1, 0, 3}
Required:
Determine the best mapping representing the function
SOLUTION:
First, find f(x) each domain value.
To find f(x), plug in the domain value into the function.
For -1, we have:
f(-1) = 2(-1)² + 5(-1) + 3
f(-1) = 2 - 5 + 3
f(-1) = 0
For 0, we have:
f(0) = 2(0)² + 5(0) + 3
f(0) = 0 + 0 + 3
f(0) = 3
For 3, we have:
f(3) = 2(3)² + 5(3) + 3
f(3) = 18 + 15 + 3
f(3) = 36
The mapping that best represents the function would be:
x (domain) ==> f(x) (range)
-1 ==> 0
0 ==> 3
3 ==> 36
The second option is the answer.
Well it's 1.35 miles and I guess you'd want it in acres and feet huh? That means it's 7128 feet and 0.22 acres
Answer:
4x^2-25x-19
Step-by-step explanation:
First off you got to distribute all the negative signs that were given. After distributing you gotta do it again to the remaining then after that, you must combine all like terms and get rid of them.
Here, you'd combine like terms.
2.5 + 3.4 = 5.9
10^4 + 10^4 = 10^8
5.9 x 10^8
