Answer 1

To find the expression (f+g)(-1), we substitute the given values for f(x) and g(x) into the expression and simplify.

Step-by-step explanation:

To find the expression (f+g)(-1), we need to substitute the given values for f(x) and g(x) into the expression.

Given that f(x) = x + 1 and g(x) = x² - x, we substitute these values into the expression:

(f+g)(-1) = (x + 1) + (x² - x)

Simplifying further, we combine like terms:

(f+g)(-1) = x + 1 + x² - x

Combining the terms, we have:

(f+g)(-1) = x² + x - x + 1

Finally, simplifying the expression, we get:

(f+g)(-1) = x² + 1
