A quadratic function f is defined by /«) = (x - 7)(x + 3). a. Without graphing, identify the x-intercepts of the graph of f. Explain how you
know.
b. Expand (x - 7)(x + 3) and use the expanded form to identify the y-intercept of
the graph of 1

Step-by-step explanation:

The two x intercepts are

x -  7 = 0

x = 7

x + 3= 0

x = - 3

The y intercept is just - 7 * 3 = - 21

To prove this  more formally

f(x) = (x - 7)(x + 3)

f(x) = x^2 - 7x + 3x - 21

f(x) = x^2 - 4x - 21

chase is right because he already been to the swings and he know how far it will be to get there

step-by-step explanation:

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
