1. **State the problem:** We are given a table of values for a function $f(x)$ and need to determine what type of function it could represent. 2. **Given values:**

1. The problem asks to find the solutions to the equation $p(x) = 0$. 2. To solve $p(x) = 0$, we need to find all values of $x$ such that the polynomial $p(x)$ equals zero.

1. The problem asks us to find the solutions to the equation $p(x) = 0$. 2. To solve $p(x) = 0$, we need to find all values of $x$ such that the polynomial $p(x)$ equals zero.

1. **State the problem:** We are given the quadratic function $$p(x) = (x - 1)^2 - 1$$ and asked to graph it. 2. **Recall the vertex form of a quadratic function:** $$p(x) = a(x -

1. The problem gives a table of values for a linear function $g(x)$ and asks to identify the x-intercept and y-intercept. 2. The x-intercept is the value of $x$ where $g(x) = 0$.

1. **State the problem:** We are given the quadratic function $$f(x) = 2x^2 - 9x - 5$$ and asked to find: (i) The coordinates of point C where the function crosses the y-axis.

1. The problem is to solve the equation $$2x + 3 = 11$$ for $x$. 2. The formula used here is to isolate $x$ by performing inverse operations. We subtract 3 from both sides and then
