The graph of a linear function \( f \) is shown. (a) Identify the slope, \( y \)-intercept, and \( x \)-intercept. (b) Write a formula for \( f \). (c) Estimate the zero of f . (a) The slope of the line is The \( y \)-intercept of the line is (Type an ordered pair.) The x -intercept of the line is (Type an ordered pair.) (b) Write a formula for f . \( \mathrm{f}(\mathrm{x})=\square \) (Type an expression using x as the variable.) (c) Estimate the zero for f . The zero of f is \( \square \).

Which graph represents the solution to the system of quadratic inequalities? \( y \geq \mathrm{x}^{2}+3 \mathrm{x}-7 \) \( \mathrm{y} \leq-\mathrm{x}^{2}+5 \mathrm{x}+2 \)
