Step-by-step explanation:
From the graph:
a) f(3) = ?
The vertical line x = 3 intersect the parabola in the point (3, -1).
Therefore f(3) = -1
b) The domain: the set of all real numbers (R) ⇒ x ∈ (-∞, ∞)
c) f(x) = 3, x = ?
The horizonatal line y = 3 intersect the parabola in the point (1, 3) (vertex).
Therefore x = 1 (f(1) = 3.
d) The domain: y ≤ 3 ⇒ y ∈ (-∞, 3]

Answer:
Step-by-step explanation:
Given
When mass = 4kg; Acceleration = 15m/s²
Required
Determine the acceleration when mass = 10kg, provided force is constant;
Represent mass with m and acceleration with a
The question says there's an inverse variation between acceleration and mass; This is represented as thus;
Convert variation to equality
; Where F is the constant of variation (Force)
Make F the subject of formula;
When mass = 4kg; Acceleration = 15m/s²
When mass = 10kg; Substitute 60 for Force
Divide both sides by 10
<em>Hence, the acceleration is </em><em />
