Given:
The function is:

This function is stretched by a factor of 9 to g(x).
To find:
The equation of function function g(x).
Solution:
The vertical stretch is defined as:
...(i)
If
, then the function f(x) compressed vertically by factor k.
If
, then the function f(x) stretched vertically by factor k.
The given function f(x) is stretched by a factor of 9 to g(x). So the value of k is 9.
Substituting
in (i), we get

![[\because f(x)=x^2]](https://tex.z-dn.net/?f=%5B%5Cbecause%20f%28x%29%3Dx%5E2%5D)
Therefore, the required function is
.
Answer:
500cm2
Step-by-step explanation:
2(9×20)+(7×20)
=360+140=500cm2
Answer:
17/24
taking L.C.M between 6 and 8
we get 24
therefore,(20-3)/24=17/24
Answer:
x=2 and y= -2
Step-by-step explanation:
Substitute y=x-4 in second equation
x-4=4x-10
get x terms on one side and numbers on other sides
4x-x=10-4
3x=6
divide 3 on both sides
x=2
substitute x=2 in y=x-4
y=2-4
y= -2
