A function f is given by
f(x)equals=StartFraction 1 Over left parenthesis x plus 5 right parenthesis squared End Fraction 1(x+5)2.
This function takes a numbe x, adds
55,
squares the result, and takes the reciprocal of that result.
a) Find
f(22),
f(0), f(a),
f(tplus+22),
f(xplus+h), and
Start Fraction f left parenthesis x plus h right parenthesis minus f left parenthesis x right parenthesis Over h End Fraction f(x+h)-f(x)h.
b) Note that f could also be given by
f(x)equals=StartFraction 1 Over x squared plus 10 x plus 25 EndFraction
1×2+10x+25
Explain what this does to an input number x.
