x={-1,0,1,2,3} 1.f=(x)=2x+3 f=(-1) = 2.f:x(2x²-4) = Tolong di jawab cepat!...

Materi Fungsi

f(x) = 2x + 3
f(-1) = 2(-1) + 3 = 1

f(2x^2 - 4) = 2(2x^2 - 4) + 3
= 4x^× - 8 + 3 = 4x^2 - 5

X = {-1 , 0 , 1 , 2 , 3}

Nomor 1
f(x) = 2x + 3

f(-1) = 2(-1) + 3
f(-1) = 1

f(0) = 2(0) + 3
f(0) = 3

f(1) = 2(1) + 3
f(1) = 5

f(2) = 2(2) + 3
f(2) = 7

f(3) = 2(3) + 3
f(3) = 9

Nomor 2
f(x) = 2x² - 4

f(-1) = 2(-1)² - 4
f(-1) = -2

f(0) = 2(0)² - 4
f(0) = -4

f(1) = 2(1)² - 4
f(1) = -2

f(2) = 2(2)² - 4
f(2) = 4

f(3) = 2(3)² - 4
f(3) = 14
