Question

Given the function G(r)=8r +4 what does G(8)=?

Answer 1

Hi there!

• Gᵣ = 8r + $4$

• Then,
for finding th' value of G(8) Substitute " 8 " in place of " r "

G₈ = 8 × 8 + 4

Multiply first, Accr'ding to B.O.D.M.A.S.

G₈ = 64 + 4

G₈ = 68

Hence, G₈ = 68

~ Hope it helps!

Answer 2

Hi there! The answer is 68.

If we want to find G(8), we must plug in r = 8 into the equation.

$g(8) = 8 \times 8 + 4$
Multiply first

$g(8) = 64 + 4$
Now add

$g(8) = 68$
Hence, the answer is G(8) = 68.
