Question

Sketch the quadratic function f(x) = -2x^2 + 4x + 6. Which key feature of the graph is not correct?A)maximum (1, 8)B)y-intercept (0, 6)C)x-intercept (3, 0)D)x-intercept (-2, 0)

Answer 1

The Solution:

A

Given the quadratic equation below:

$f(x)=-2x^2+4x+6$

We are asked to identify the option that is incorrect.

Below is the graph of the given equation:

From the graph above, we have that x-intercept (-2,0) is incorrect.

Therefore, the correct answer is [option D]
