Answer:

The vertical intercepts is

(4/3,0) (3,0) (1,0)

The horinzontial intercepts is

(0,72)

The end behavior is

<em>as x approaches positive infinity, f(x) approaches negative infinity. As x approaches negative infinity, f(x) approaches negative infinity.</em>

Step-by-step explanation:

The vertical or y intercepts will be zeroes of the following factors.

3x + 4 = 0

x - 1 = 0

(x - 3) {}^{2}  = 0

We solve for x each time.

x =  -  \frac{4}{3}

x = 1

x = 3

Part B). We need to find the intercepts by setting the equation equal to zero.

The constant expanded will equal 72.

If x=0,

{0}^{y}  = 0

where y is any real number.

So this means all the exponets will equal 0. The constant will just add to the term. so our horinzontal intercept is

0 + 72 = 72

Part C) End Behavior

The leading degree is even. Even Degree Polynomials like Quadratics tend to go approach positive infinity vertically as x approaches positive infinity, and as x approaches negative infinity, it approaches positive infinity vertically.

Our leading coefficient is negative so this means our quadratic will get reflected across the x axis.

Now this means, as x approaches positive infinity, f(x) approaches negative infinity. As x approaches negative infinity, f(x) approaches negative infinity.

david took 10 1/2 hours over 3 days to build airplane. he spent 3 1/4 hrs the firsr day and 4 2/3 hours the second day. how many
Anuta_ua [19.1K]
2 7/12 hours

X=101/2 - ( 3+4+1/4+2/3)

X=101/2 - 7 + (1/4+2/3)

1/4+2/3= 11/12

101/2 - 7 =3 1/5

X = 3 1/5 - 11/12 = 2 7/12

Line L1, L2 and L3 are in the same plane, L1 is perpendicular to L2, and L3 is parallel to L1. which of the following statement
exis [7]
Only Statement 2 is surely correct.
because there maybe chances that the line L1 and L3 lies above the line L2 and they can also fulfill the condition of perpendicularity so we can't be sure about statement 3 & statement 1 is clearly incorrect

Give an estimate of the mean hardness that you would expect after 37 and 41 hours; and a 85% confidence interval for each estima
Jlenok [28]
The predicted value of hardness at 37 hours is 243.87 and an 85% confidence interval for the mean hardness is (242.12, 245.61). At 41 hours, the predicted hardness is 252 and an 85% confidence interval for mean hardness is (249.83, 254.18). The confidence interval for X is equals to 41 which is wider because the value 41 is farther away from the sample mean X than is 37. As an outcome, the standard error for the prediction is larger.
