Question

Use a graphing calculator to evaluate all zeros. What are the zeros? (Use commas to separate answers. Round to the nearest thousandth.)f(x)=4x^2 -2x-3

Answer 1

Solution

The graph of the function

$f(x)=4x^2-2x-3$

is given below

To find the zeros of the function from the graph, we only need to check the x - intercept on the graph

Therefore, the zeros of f(x) are

$x=-0.651,1.151\text{ (to the nearest thousandth)}$
