Answer:
Step-by-step explanation:
Piecewise function 'f' has been given as,
f(x) = 4x + 3 when x < 0
(x + 7) when x ≥ 0
By using the piecewise function,
a). f(-2) = 4(-2) + 3 (Use f(x) = 4x + 3, since x = -2 is less than 0)
= -8 + 3
= -5
b). f(0) = 0 + 7 (Use f(x) = x + 7, since x = 0 is equal to 0)
= 7
c). f(1) = 1 + 7 (Use f(x) = x + 7, since x = 1 is greater than 1)
= 8
Answer:
Protractor
Step-by-step explanation:
A POSTULATE, LAW OR THEORY SHOULD NEVER BE ALTERED
∴ The protractor postulate states that the measurement of an angle between two rays can be designated as a unique number, and this number would be between 0 and 180 degrees, Hence for every angle A, there corresponds a positive real number less than or equal to 180. This postulate guarantee the use of a protractor to measure angles.
Hence, Given line AB and point O on that line in such a way that any ray that can be drawn with its endpoint at O can be put into a one- to-one correspondence with the real numbers between 0 and 180 is a statement that explains Protractor's Postulate.
