Jika F(t) = 4t + 7, maka F(3+h) - F(3) / h = A. -4 B. 4 C. 0 D. H E. 4H

Saya bantu jawab ya.

MATEMATIKA
Fungsi

f(t) = 4t + 7

f(3+h) - f(3) / h = (4(3 + h) + 7) - (4(3) + 7) / h

= (4(3 + h) + 7) - (4(3) + 7) / h
= (12 + 4h + 7) - 19 / h
= 12 + 4h + 7 - 19 / h
= 4h / h
= 4

Maka f(3+h) - f(3) / h = 4. (B)
