Answer:
Part 1) [tex]f(-3)=21[/tex]
Part 2) [tex]g(3)=9+21r[/tex]
Step-by-step explanation:
Part 1) Find the value of f(-3)
we have
[tex]f(x)=-6x+3[/tex]
we know that
f(-3) is the value of the function f(x) for x=-3
so
substitute the value of x=-3 in the function to find f(-3)
[tex]f(-3)=-6(-3)+3[/tex]
[tex]f(-3)=18+3[/tex]
[tex]f(-3)=21[/tex]
Part 2) Find the value of g(3)
we have
[tex]g(x)=3x+21r[/tex]
we know that
g(3) is the value of the function g(x) for x=3
so
substitute the value of x=3 in the function to find g(3)
[tex]g(3)=3(3)+21r[/tex]
[tex]g(3)=9+21r[/tex]
