Answer:
B
Step-by-step explanation:
Given that the function h(x) = 2x-9 is translated up 5 united to become a new function, i(x)
To find: Equation of new function
The graph of a function can be moved up, down, left, or right by adding to or subtracting from the output or the input.
Adding to the output of a function moves the graph up
Therefore,
Given function is:
h(x) = 2x - 9
Translated up by 5 units
Therefore, new function is:
i(x) = h(x) + 5
i(x) = 2x - 9 + 5
i(x) = 2x - 4
Thus Option B is correct
Answer:
25%
Step-by-step explanation:
Mrs. Loar has to grade 75 papers. Mrs. Holt is helping her grade. Mrs. Loar graded 60 papers and Mrs. Holt graded the rest.
Hence, the amount of papers Mrs Holy graded is = 75 - 60
= 15 papers
What percent of the papers did Mrs. Holt grade?
This is calculated as:
15/60 × 100 = 25%
Hence, Mrs Holy graded 25% of the papers
Answer:
- (-1, -5), (-1/2, -3), (-1, -9)
Step-by-step explanation:
<u>The function in vertex form is:</u>
- f (x) = a(x - h)² + k, where (h, k) is the vertex
- f(x) = (x - 1)² - 3
i) y = f(x) - 2 = (x - 1)² - 3 - 2 = (x - 1)² - 5 ⇒ h = 1, k = -5
<u>Minimum point:</u>
ii) y = f(2x) = (2x - 1)² - 3 = 4(x - 1/2)² - 3 ⇒ h = 1/2, k = -3
<u>Minimum point:</u>
iii) y = 3f(x) = 3((x - 1)² - 3) = 3(x - 1)² - 9 ⇒ h = 1, k = -9
<u>Minimum point:</u>
