11. Diketahui rumus fungsi f(x) = 7x-5. Nilai dari f(1) – f(0) adalah. . .
fungsi linear
–
f (x) = 7x – 5
shg,
f (1) – f(0) = { 7(1) – 5 } – { 7(0) – 5 }
f (1) – f(0) = 2 – ( -5 )
f (1) – f(0) = 7
____
Penjelasan dengan langkah-langkah:
f(x) = 7x – 5
- f(1) – f(0)
- = (7(1) – 5)) – (7(0) – 5))
- = (7 – 5) – (-5)
- = 2 – (-5)
- = 2 + 5
- = 7
