Question 1121194

Let f(x) = 2-x2, evaluate (a) f(x+1) and (b) f(x)+f(1).
my answer to 
a. is x^2-2x+1
b. ?
<pre>Your answer to a) is incorrect. Instead it should be: {{{highlight_green(matrix(1,4, "a.", f(x + 1), "=", - x^2 - 2x + 1))}}}
{{{highlight_green(matrix(1,6, "b.", f(x) + f(1), "=", 2 - x^2 + 2 - 1^2, "=", 3 - x^2))}}}
