Answer:
y = 14 
Step-by-step explanation:
For an exponential function of the form y = a
Use the given points to find a and b
Using (0, 14 ), then
14 = a
( = 1 ) , thus
a = 14
y = 14
Using (3, 3024 ) , then
3024 = 14 b³ ( divide both sides by 14 )
216 = b³ ( take the cube root of both sides )
b = ![\sqrt[3]{216}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B216%7D)
= 6 , thus
y = 14 × 
← exponential function
Answer: y = 1/2x - 7
<u>Data</u>
Point = (-4, -9)
slope = m = 1/2
<u>Process</u>
To solve this problem, use the formula slope- y-coordinate, substitute the values and simplify.
<u>Equation</u>
y - y1 = m (x - x1)
x1 = -4
y1 = -9
<u>Substitution</u>
y + 9 = 1/2 (x + 4)
<u>Simplification</u>
y + 9 = 1/2x + 4/2
y = 1/2x + 2 - 9
<u>Answer</u>
y = 1/2x - 7
The answer is D because the range is all the y-values.
Answer:
B: (-7, -8)
Step-by-step explanation:
If the midpoint of (-3, 4) is (-5, -2), then the difference in x is 2, and the difference in y is 6. So to get from the midpoint to b, you have to add two to the x value, and add 6 to the y value. This gets us to the point (-7, -8).
*Hope this helped! : )*
After simplifying, that answer would be -65
