Question

Referring to the figure, match the function with its graph.
y = (x - 3)(x + 4)
a. See figure
b. See figure
c. See figure

Answer 1

ok

Answer 2

so (x-3) and (x+4) are factors, which mean they are the values of x that make y = 0.
x-3 = 0
x = 3

x+4 = 0
x = -4

So the graph with x-intercepts at 3 and -4 is the one we are looking for.

Answer 3

work out the values of x when the function is zero - this will help

Answer 4

Okay so it would be B? @twistnflip

Answer 5

there you go! awesome job
