Answer:
linear
Step-by-step explanation:
First differences of the y-values for the consecutive x-values are ...
-3 -(-4.5) = 1.5
-1.5 -(-3) = 1.5
0 -(-1.5) = 1.5
1.5 -0 = 1.5
The first differences are constant, so the function is linear.

Since we know the function is linear, there's no real point in computing the ratios of successive outputs. In any event, we know it is not constant. The ratio with 0 as a numerator will be 0; the ratio with 0 as a denominator will be undefined.
A polynomial with a degree of 3 is understood to have three zeroes or roots. In the given problem in 1, x3 + 6 x2 – 9x – 54, the roots of the polynomial using the calculator are B. B. 3, -3, -6. The same applies for number 2 given the polynomial x3 – 4x2 + 3x – 12. The answer in 2 is D. 4 years. The roots of the polynomial in 3 are:
<span>x1=−0.45117</span>
<span><span>x2</span>=1.77474</span>
<span><span>x3</span>=0.03821+0.70576∗i</span>
<span><span><span>x4</span>=0.03821−0.70576∗i. Hence there is A. 1 negative root.</span></span>
The answer is: b) a = 63°
