Hi I’m so bad at math, please help me

See below.

Step-by-step explanation:

We need to figure out the function of g(x) first.

y=mx+b

7=2x+b

5=4x+b

Subtract the first from the second.

2x=-2

x=-1

Plug back into the equation.

7=-2+b

b=9

y=-x+9

A.  The y-intercept of the function f(x) is less than the y-intercept of g(x).

The y-intercept of f(x) is 8 and of g(x) is 9.  This is true.

B.  Function f(x) is non-linear.  This is true.

C.  Function f(x) has more x-intercepts than g(x).  f(x) does not have any x-intercepts.  g(x) has 1.  This is false.

D.  The y-intercept of the function f(x) is greater than the y-intercept of g(x).  Since A is true, this must be false.

E.  The y-intercepts of f(x) and g(x) are equal.  This is false, since A is true.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
