M = 0.25k + 5
OLinear Function
O NON-linear Function

OLinear Function

Step-by-step explanation:

In general ,A linear function has the form y = ax + b

so ,the function :

m = 0.25k + 5  is linear .

We just changed

m to y

x to k

a to 0.25

b to 5

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
