1. Aşağıdaki ifadelerin tanımlı olduğu aralıklar- da fonksiyon olup olmadıklarını bulunuz.
a) f: R-R, f(x) = 2x + 5
b)f: R-R, f(x) = x2+1
c)f: R-R, f(x) = X-5
x+1
Ç) : Z – Z, F(x) = 32

step-by-step explanation:

114 plus 113 times 2 and 114 times 3

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
