Question

Find the value of f(-3) and g(3) if f(x) = -6x + 3 and g(x) = 3x + 21r.

Answer 1

Answer:

Part 1) $f(-3)=21$

Part 2) $g(3)=9+21r$

Step-by-step explanation:

Part 1) Find the value of f(-3)

we have

$f(x)=-6x+3$

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)

$f(-3)=-6(-3)+3$

$f(-3)=18+3$

$f(-3)=21$

Part 2) Find the value of g(3)

we have

$g(x)=3x+21r$

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)

$g(3)=3(3)+21r$

$g(3)=9+21r$
