All Parent functions have both x- intercepts and y-intercepts EXCEPT. I. Linear II. Absolute Value III.Quadratic IV. Cubic V.Squ

stealth61 [152]

Answer:

Reciprocal, Exponential and Logarithmic.

Step-by-step explanation:

x intercept is the value of x where y value is 0.

y intercept is the value of y where x value is 0.

Let us have a look at the possibility for <em>each parent function </em>as given.

I. Linear

$y =x$

When x = 0, y = 0 and

When y = 0, x = 0

Therefore, both x and y intercept exist.

II. Absolute value

$y =|x|$

When x = 0, y = 0 and

When y = 0, x = 0

Therefore, both x and y intercept exist.

III. Quadratic

$y =x^{2}$

When x = 0, y = 0 and

When y = 0, x = 0

Therefore, both x and y intercept exist.

IV. Cubic

$y =x^3$

When x = 0, y = 0 and

When y = 0, x = 0

Therefore, both x and y intercept exist.

V. Square root

$y =\sqrt x$

When x = 0, y = 0 and

When y = 0, x = 0

Therefore, both x and y intercept exist.

VI. Cube root

$y =\sqrt[3]x$

When x = 0, y = 0 and

When y = 0, x = 0

Therefore, both x and y intercept exist.

VII. Reciprocal

$y =\dfrac{1}x$

When $x = 0, y \rightarrow \infty$

Therefore, both x and y intercept do not exist.

VIII. Exponential

$y =b^x$

where b is any base:

When $x = 0, y =1$ therefore y intercept exists.

When we put y = 0, which is not possible

Therefore, both x and y intercept do not exist.

IX. Logarithmic

$y =logx$

When $x = 0, y \rightarrow$ not defined

Therefore, both x and y intercept do not exist.

The cost of renting Party Palace is $ 120 plus $ 15 per person attending the party. If the total cost of renting Party Palace is

aalyn [17]

Answer:

24 individuals

Step-by-step explanation:

Since we are given the actual costs as well as the final total then we can calculate the total number of people that attended the party by doing the following. We first subtract the fixed cost of $120 by the total cost of the party, and then we divide the remainder by the cost per person, which would give us the number of people who attended (x) ...

($480 - $120) / $15 = x

$360 / $15 = x

24 = x

Finally, we can see that a total number of 24 individuals attended the party

Please help with geometry, you will get crown or smthin

den301095 [7]

Answer:

52√3 ft ²

Step-by-step explanation:

Formula for area of the trapezoid:

$A=\frac{a+b}2h$

a = Base = 11

b = Base = 15

h = Height = 4√3

Since the height is 4√3 we can turn it into a number:

4√3 = 6.92820323028 = 6.93

Now using the formula:

$A=\frac{a+b}2h=\frac{11+15}2\times6.93=90.06664$ $=90.07$

As you can see that it not a answer choice.

We can turn the answer choice into number:

44√3 ft ² = 76.21023553.. ≈ 76.20

44√3-24 ft ²=52.21023553.. ≈ 52.20

60√3 ft ² = 103.92304845.. ≈ 103.90

52√3 ft ² = 90.06664199.. ≈ 90.07

Thus, the answer is 52√3 ft ²
