Answer:
Option a - f(x)=20x
Step-by-step explanation:
Given : For a certain function f = f(x), we know that f is proportional to x and that the constant of proportionality is 20.
To Find : A formula for f ?
Solution :
We have given that,
f is proportional to x i.e.
This implies
Where, k is the proportionality constant
The constant of proportionality is 20.
So,
On comparing with, f = f(x)
Therefore, The formula of f is
So, Option a is correct.
Answer:
Option C is correct.
Step-by-step explanation:
The equation used to represent the slop-intercept form is
y= mx + b
where m is the slope
and b is the y-intercept.
So, in the given question y-intercept = (0,8)
b= 8 and
slope =m= 1/2
the equation will be:
y = mx + b
y= (1/2)x + 8
So, Option C is correct.
