Answer: A) 7 real zeros and 6 turning points at 0, 2, 4
<u>Step-by-step explanation:</u>
x⁷ - 6x⁶ + 8x⁵
The degree (largest exponent) is 7 so the maximum number of real zeros is 7.
<u>Factor out x⁵</u>
x⁵(x² - 6x + 8)
<u>Factor the quadratic</u>
x⁵(x - 2)(x - 4)
<u>Set each factor equal to 0 and solve for x</u>
x⁵ = 0 --> x = 0 (multiplicity of 5)
x - 2 = 0 --> x = 2
x - 4 = 0 --> x = 4

Answer: -2
Step-by-step explanation:
The equation of a line in slope - intercept form is given as :
where m is the slope and c is the y - intercept.
Equation given :
⇒ 
add 9 to both sides , we have
comparing with :
slope = -2
