Evaluate: f(x) = f(g( wheref(x)= 3x-2 and g(x)= x^2-4

Hello from MrBillDoesMath!

Discussion:

Evaluate f(g(3)).

g(3) = 3^2 -4 = 5 so

f(g(3)) = f(5) = 3*5-2 = 15 -2 = 13

Thank you,

Step-by-step explanation:

g(3)=3^2-4

g(3)=9-4

g(3)=5

f(x)=f(5)

f(5)=3(5)-2

f(5)=15-2

f(5)=13

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
