Find an equation of the red line in FIGURE 6.1.10 e, xs0 (-e", x > 0 50. f(x) 52. Find the total area of the shaded region in FIGURE 6.1.11. Calculator Problems In Problems 53 and 54, use a calculator to fill out the given table. 53. 10 100 1000 10,000 100,000 1.000,.000Explanation / Answer
46) f(x) = b^x
a) f(x+h) - f(x) / h
f(x+h) = b^(x+h)
f(x+h) - f(x) / h = [ b^(x+h) - b^x ] / h
= [ b^x * b^h - b^x ] / h
= b^x [ ( b^h - 1 ) / h ]
which is right side
b) f(x1 + x2 ) = f(x1) f(x2)
f(x1) = b^x1
f(x2) = b^x2
b^(x1 + x2) = b^x1 * b^x2
which means
f( x1 + x2 ) = f(x1 ) + f(x2 )
according to the laws of exponents whan base is same exponents are added
