#1</h3>
Given: f(x) = 3x² -5x + 4
To find f(-2), simply substitute x = -2 in function f(x).
f(-2) = 3(-2)² -5(-2) + 4
f(-2) = 12 + 10 + 4
f(-2) = 26
Answer: 26
<h3>#2</h3>
For an ordered pair (x, y) in a relation, the y element represents the range.
Answer: range
Answer:
71.9
Step-by-step explanation:
Whenever you want to round a number to a particular digit, look only at the digit immediately to its right. For example, if you want to round to the nearest tenth, look to the right of the tenths place: This would be the hundredths place digit. Then, if it is 5 or higher, you get to add one to the tenths digit.
Answer:
I think it's 7
Step-by-step explanation:
-6 < 2T (-5+5) < 3+5
-6 < 2T < 8
+6 < 2T < 8 + 6
0 < 2T < 14
0 < ÷ 2 < ÷ 2
0 < T < 7
-0 < T < -0
T = 7
Perimeter = 2l + 2w
Divide 184 by 4
184/4 = 46
Subtract by 6
46 - 6 = 40
Add by 6
46 + 6 = 52
The length is 52, and the width is 40.
We can verify by plugging these values into the original equation.
52*2 + 40*2 = 184
Answer:
Step-by-step explanation:
First of all, your question is very clear. Excluding 0 is a needed restriction.
f(1) = 3*1 + 1 = 3 + 1 = 4
f(2) =3*2 + 1 = 6 + 1 = 7
f(3) = 3*3 + 1 = 9 + 1 = 10
f(4) = 4*3 + 1 = 12 + 1 = 13
4,7,10,13
Notice that you are just adding 3 to the previous term.
