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.
Answer:
d
Step-by-step explanation:
75 per week,
after 13 weeks, 75*13 = 975
No.
The rule for dividing exponents is: if the bases are the same, keep the base and subtract the powers.
m^12/m^4=m^8
Answer:
28=x
78=y
Step-by-step explanation:
The lines are perpendicular so 78 would be the same for the top line. So the equation fill in would be (5x-62)=78 turning x into 28
You are right with multiplying 100 and 3. An easier way to do it is to divide 300 and 4, so you can get the blank.
