Can anyone help ? ASAP

3a+7

g(a) = 4a+4

f(a) = a-3

g(a) - f(a) = (4a+4) - (a-3)

                   4a+4 - a+3 ; 4a-a=3a , 4+3=7

                   3a+7

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
