Aquadratic equation in standard from is written ax^2= bx+c, where a, b and c are real numbers and a is not zero?

If f(x)=-3x+2 and g(x)=-7x-2, which point represents f(x)=g(x)?

The graph of the function f(x) = (x + 2)(x + 6) is shown below. which statement about the function is true? the function is positive for all real values of x where x > –4. the function is negative for all real values of x where –6 < x < –2. the function is positive for all real values of x where x < –6 or x > –3. the function is negative for all real values of x where x < –2.
