Answer:
21
Step-by-step explanation:
6 times because 6•7=42 so it must be 6 because 7•7=49
Good luck!!
Step-by-step explanation:
f(x) = -7x² - x
g(x) = 9x² - 4x
(f - g)(x) = (-7x² - x) - (9x² - 4x)
(f - g)(x) = (-7x² - 9x²) + (-x + 4x)
(f - g)(x) = -16x² + 3x
(f - g)(1) = -16(1)² + 3(1)
(f - g)(1) = -16.1 + 3
(f - g)(1) = -16 + 3
(f - g)(1) = -13
Y intercept is (0,-2)
Zeros are the x intercepts which are (-7,0) (-3,0) (5,0)
