Answer:

gof(x) = x²+8x+15

Step-by-step explanation:

gof(x) = g(f(x))

f(x) = x + 4 and g(x)=x²-1

Substituting

gof(x) = g(f(x)) = g(x + 4) = (x+4)²-1

gof(x) = x²+8x+16 -1 = x²+8x+15

That is if f(x) = x + 4 and g(x)=x²-1, gof(x) = x²+8x+15

Answer:

162 mL

Step-by-step explanation:

1.Convert all volumes to millilitres

(a) Chlorpheniramine

V = 100 mL

(b) Lidocaine

$V = \text{2 fl oz} \times \dfrac{\text{29.57 mL}}{\text{1 fl oz}} = \textbf{59 mL}$

(c) Banana flavouring

$V = \dfrac{1}{2}\text{ tsp} \times \dfrac{\text{4.928 mL}}{\text{1 tsp}} = \textbf{2.5 mL}$

2.Calculate the total volume

Chlorpheniramine = 100 mL

Lidocaine = 59

Banana flavouring = <u> 2.5 </u>

TOTAL = 162 mL
