Answer:
yes because When you are given an equation and a specific value for x, there should only be one corresponding y-value for that x-value. For example, y = x + 1 is a function because y will always be one greater than x. Equations with exponents can also be functions.
Step-by-step explanation:
The notation y = f(x) defines a function named f. This is read as “ y is a function of x.” The letter x represents the input value, or independent variable. The letter y, or f(x), represents the output value, or dependent variable.
Answer:
42km
Step-by-step explanation:
Answer:
Step-by-step explanation:
We want to find the inverse of
We interchange x and y.
We need to solve for y, so let us multiply through by 2.
Subtract 6 from both sides.
Therefore the required inverse is
Answer:
20% , just trust me. its 20%
Step-by-step explanation:
Answer:
---- critical point
local minima
Step-by-step explanation:
Given
Required
Determine the critical point
Differentiate w.r.t x
Differentiate w.r.t y
Equate both to 0
Divide by 2
----- in both equations
Hence:
The critical point is:
Solving (b):
We have:
This is represented as:
Calculate the determinant
The critical point is at local minima
