1. The problem asks whether the statement "As $x$ goes to positive infinity, $f(x)$ goes to positive infinity" is true or false for the given graph. 2. From the graph description,

1. Let's clarify the given expressions about the complex number $z$: - $z$ alone is the complex number itself.

1. The problem states: Given the function $f : [1, \infty) \to [1, \infty)$ defined by $$f(x) = 2^{x^{x-1}},$$

1. The user requests to solve a problem using only formulas, without options. 2. Since no specific problem is provided, I'll explain the general approach to solving algebraic equat

1. **Stating the problem:** We are given the function $$f : [1, \infty) \to [1, \infty)$$ defined by $$f(x) = 2^{x^{x-1}}$$. We need to find the inverse function $$f^{-1}(x)$$.

1. The problem is to find the degree of a polynomial or expression. 2. The degree of a polynomial is the highest power of the variable in the expression with a nonzero coefficient.

1. We are asked to expand the expression $$(x+4)(x-5)(x+3)$$. 2. First, expand two of the factors, for example, $(x+4)(x-5)$:

1. Stating the problem: Simplify the expression $$\sqrt{10^{400} \div 10^{220} \times 10^{80}}$$. 2. Apply the division rule for exponents: $$10^{400} \div 10^{220} = 10^{400-220}
