Answer:
<h2>7</h2>
Step-by-step explanation:
To find f(-2) , Substitute -2 for x in the given equation ;
To find g(f(-2)) ;
To find g(2) , substitute 2 for x in the given equation
first work out the value of 2 bags of chips which is: 0.75 + 0.75 = 1.50p
take that away from the total: 22.50-1.50=21 pounds
since what is left (21) is how much 4 ham sandwiches cost we can just divide 21 by 4 which is 5.25
so each sandwich costs 5.25 pounds

Answer:
x² + 8
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 2x² + 1 - (x² - 7)
= 2x² + 1 - x² + 7 ← collect like terms
= x² + 8
