f x 4x2 6 f a h f a f a h Solutionfx4x26 fa4a26 fah 4

f (x) = 4x² + 6

f (a + h)

f (a)	=
f (a + h)	=
$\"(f(a+h)-f(a))/h\"$	=

f(x)=4x²+6

f(a)=4a²+6

f(a+h)= 4(a+h)²+6=4a²+4h²+8a h+6

Therefore difference quotient=(f(a+h)-f(a))/h=4h+8a

f (x) = 4x2 + 6 f (a + h) f (a) = f (a + h) = = Solutionf(x)=4x2+6 f(a)=4a2+6 f(a+h)= 4(a+h)2+6=4a2+4h2+8a h+6 Therefore difference quotient=(f(a+h)-f(a))/h=4h+
