I would make a table and plug values(or just plug in x values) in to figure out the equation's graph: (plug in values that will make it easy for you since you have a √)
f(x) = 3(√x)
x = 0
f(0) = 3(0) = 0 ------> (0 , 0)
x = 1
f(1) = 3(√1) = 3(1) = 3 ------> (1 , 3)
x = 4
f(4) = 3(√4) = 3(2) = 6 ------> (4 , 6)
Now that you have found some points, find a graph/line that goes through these points

Answer:
- Find the coefficients using ax^2 + bx + c = 0
a = 4
b = 7
c = 0
- Make the coefficient equal 1. But how do we do that? Division.
4n² + 7n = 0
4/4n² + 7n/4 = 0/4
= n² + 7/4n = 0
a = 1
b = 7/4
c = 0
- Complete the square using b/2².
b = 7/4
(b/2)² = (7/4 ÷ 2)²
Use fraction rule.
7/4 ÷ 2² = 7/4² / 2²
<em>square the numbers</em>
7/4² / 2² = 49/16 ÷ 4
49/16 ÷ 4 = 49/16 × 1/4
49/16 × 1/4 = 49/64
Add to both sides of the equation using 49/64
b = 7/4
b/2 = 7/4 ÷ 2
<em>simplify</em>
b/2 = 7 ÷ (4 × 2)
<em>simplify(arithmetic)</em>
b/2 = 7/8
n² + 7/4n + 49/64 = 49/64
(n + 7/8)² = 49/64
Next, cancel out the square on the left side.
Subtract 7/8 from both of the sides.
Simplify the left side.
<em>That wraps it up for this equation. Hope it helped!</em>
Answer:
1/8 of 60 is 7.5
Step-by-step explanation:
2/1 or just 2 is the steepest, because it is the closest to the y-axis.
Steepest slope is: 2/1 or just 2
Steep but not that is: 3/5
Not steep is: 1/3
