Question

f(x)=5(x+2)
a)find
(i)f(2)
(ii)f(6)
(iii)f(-3)

Answer 1

Step-by-step explanation:

given f(x)=5(x+2)

f(2)=5(2+2)

=5(4)

=20

f(6)=5(6+2)

=5(8)

=40

f(-3)=5(-3+2)

=5(-1)

=-5

Answer 2

Answer:

if f(x) = 5(x+2)

f(2) = 5( 2 + 2)

= 20

f(6) = 5 (6+ 2)

= 40

f(-3) = 5 (-3+2)

= 5 x -1

= -5

Allways substitute the value inside the function instead of x
