Please help! Select the only equation type that can be modeled as a continuous linear function

Question 1 options:

f(x)=12x

f(x)=5x−3

f(x)=x2−7

f(x)=f(x−1)×2, f(1)=4

A.

Step-by-step explanation:

f(x) = 12x

since here, x>=0, the function will be continous as a linear And will have a straight lined graph

answer: it is d

step-by-step explanation:

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
