The linear function whose points are given is f(x)=
Given the points of the function f(-10)=-1,f(0)=1,f(10)=3.
We are required to find the function whose points are given.
Function is relationship between two or more variables that are expressed in equal to form. In function each value of x must have a corresponding y value.
x value is known as domain and y value if known as codomain of the function.
Take two points (-10,-1) and (0,1) and we can form one equation as under:
y+1=(1+1/0+10) * (x+10)
y+1=2/10 (x+10)
y+1=x/5 +10/5
y+1=x/5+2
y=x/5+2-1
y=x/5+1
Hence the linear function whose points are given is

Answer:
y = 57
Step-by-step explanation:
y α x
y = kx ; k = Constant of proportionality
81 = k* 54
k = 81/54
k = 1.5
Value of y when x = 38
y = kx
y = 1.5 * 38
y = 57
Hence, y = 57 when x = 38
