Graphs are used to put numbers in a visual form, like a bar graph showing population growth over time. Their advantage is that it helps the viewer understand the situation by seeing it in a easier way.
Answer:
f(x) = 4x² + 9x - 28
Step-by-step explanation:
Create the polynomial by multiplying (4x - 7) and (x + 4) together:
f(x) = 4x² + 16x - 7x - 28, or
f(x) = 4x² + 9x - 28
