The x-intercepts of the graph of 4x² + 25x - 21 are 3/4 and -7. the correct option is b. Three-fourths, negative 7
From the question, we are to sketch the graph of the given quadratic expression
The given quadratic expression is
4x² + 25x - 21
The graph of 4x² + 25x - 21 is shown in the image below
From the graph,
We can observe that the graph cuts the x - axis the points x = -7 and x = 3/4
∴ The x - intercepts of the given quadratic are -7 and 3/4
Hence, the x-intercepts of the graph of 4x² + 25x - 21 are 3/4 and -7. the correct option is b. Three-fourths, negative 7
