Question

What are the x– and y–intercepts of the graph of y = x^2 + 7x + 12?

x–intercepts: (–3, 0) and (–4, 0)
y–intercept: (0, 12)

x–intercepts: (–3, 0) and (4, 0)
y–intercept: (0, –12)

x–intercepts: (3, 0) and (4, 0)
y–intercept: (0, –12)

x–intercepts: (3, 0) and (–4, 0)
y–intercept: (0, 12)

Answer 1

y intercept when x= 0 = 12 coordinates are (0,12)
x intercept when y = 0:
y = (x+3)(x+4) = 0
solve to get x values and plug into expression to get y coordinates
