Answer:
The value of f(3) is 8 ⇒ D
Step-by-step explanation:
- In the function f(x) = y, y is the corresponding value of x
- Ex: If f(a) = b, then the value of y = b at x = a
Let us solve the question
∵ The given figure represents the function f(x)
→ That means every point on the graph represents f(x) = y
∴ f(x) = y
∵ We need to find f(3)
→ That means we need the value of y at x = 3
∴ x = 3
Look at the graph and find the y-coordinate of the point that lies on the curve and has x-coordinate = 3
→ Each small square on the x-axis represents 1 unit, and on the y-axis
represents 2 units
∵ There is a point on the graph that has x-coordinate = 3
∵ The y-coordinate of this point is 8
∴ The point (3, 8) lies on the graph of f(x)
∴ x = 3 and y = 8
∴ f(3) = 8
∴ The value of f(3) is 8
<h3><u>Question:</u></h3>
A pyramid has a square base with sides of length s. The height of the pyramid is equal to 1/2 of the length of a side on the base. Which formula represents the volume of the pyramid?
<h3><u>Answer:</u></h3>
<em><u>The formula represents the volume of the pyramid is:</u></em>

<h3><u>Solution:</u></h3>
<em><u>The volume of square pyramid is given by formula:</u></em>

Where, "h" is the height of pyramid
"a" is the length of side of base
Here given that, pyramid has a square base with sides of length s
Therefore,
a = s
The height of the pyramid is equal to 1/2 of the length of a side on the base

<em><u>Thus the volume of pyramid becomes:</u></em>


Thus the formula represents the volume of the pyramid is 
Answer:
25
Step-by-step explanation:
so you replace all the x's with 15 and it becomes
2×15-5
2×15=30
30-5=25
