<h2><u>
Answer:</u></h2>
y = cos ^- 1 (x)
Step-by-step explanation:
The Function y = cos -1x = arccos x and its Graph: Since y = cos -1x is the inverse of the function y = cos x, the function y = cos -1x if and only if cos y = x. This leaves the range of the restricted function unchanged as [-1, 1].

Answer:
5x^2 +  3x   +4
Step-by-step explanation:
(2x^2 + x + 3) + (3x^2 + 2x + 1)
Combine like terms
(2x^2 + 3x^2 + 2x+ x + 3 + 1)
5x^2 +  3x   +4
