Exercise 3L Use your GDC to plot the graph of the quadratic function. Then use the graph to find the coordinates of the x-intercept, the y-intercept and the vertex of the graph. 1 f(x)=3x²+7x-4 2 f(x)=-4.2x²+6.1x-3

Q: Use the vertex and intercepts to graph the quadratic function f (x) = -x² + 2x + 3.

A: Here I will first find the intercepting points then I will draw this graph using this intercepts and…

Q: Sketch the graph of the quadratic function and the axis of symmetry. State the vertex, and give the…

A:

Q: Identify  the vertex, intercepts, and  the axis of symmerty of quadratic function f(x)= -3x2-9x+7

A: First we will make a perfect square to find the vertex and axis of symmetry.
