Answer:
g(x) =
Step-by-step explanation:
Parent function given in the graph attached is,
f(x) =
Function 'f' passes through a point (1, 1).
If the parent function is stretched vertically by 'k' unit,
Transformed function will be,
g(x) = k.f(x)
Therefore, the image of the parent function will be,
g(x) =
Since, the given function passes through (1, 2)
g(1) = = 2
⇒ k = 2
Therefore, image of the function 'f' will be,
g(x) =
Answer:
8a+7b
Step-by-step explanation: 6+2=8 3+4=7
He should expand the 1/4 on the barker (x+12) then he will have 1/4x+3 = 2 then he should subtract the 3 from the 2 meaning he will be left with 1/4x = -1 and then he should multiply the left hand side and the right hand side with 4 in order to get rid from the 1/4 so the answer is x = -4

Answer:
Average grade for this test = 1.85
Step-by-step explanation:
Given that number of students receiving respective grade scores are : 11, 18, 52, 13, 6
Then total number of students = 11 + 18 + 52 + 13 + 6 = 100
Sum score obtained by total students
= 11F + 18D + 52C + 13B + 6A
= 11(0) + 18(1) + 52(2) + 13(3) + 6(4)
= 0 + 18 + 104 + 39 + 24
= 185
Now average grade for this test is given by 185/100 = 1.85
Hence final answer is 1.85.
