I need a step by step on how to solve these algebra 2 problems.
1.Consider the function f(x)=2x² + 7x-15
Find the y-intercept, the equation of the axis of symmetry, and the x-cord of the vertex.
Then graph the function by making a table of values.
2. Determine whether f(x)=-2x²-4x+6 has a maximum or a minimum value. then find this maximum or minimum value and state the domain and range of the function.
3.Solve -x²+2x+4=0 by graphing. If exact roots cannot be found, state the consecutive integers between which the roots are located. (obviously you cant graph but explain the steps involved
