Answer:
slope = - 44
Step-by-step explanation:
the derivative of f(x) at x = 3 is the slope of the tangent line
f(x) = -6x² - 8x + 5
differentiate using the power rule
f'(x) = - 12x - 8
f'(3) = - 36 - 8 = - 44 ← slope of tangent line at (3, 4 )
Test statistic:
z = (0.67 - 0.63) / 0.033 = 1.21
p - Value = P(z > 1.21) = 0.106
My conclusion: Fail to reject null hypothesis
No, there is no evidence of a difference
Im not good at these so maybe 105°? Sorry if its wrong
go up 8, go left -4
