Answer: (f-g)(4)=46
Step-by-step explanation:
(f-g)(4) means f(4)-g(4). We first need to find the values of f(4) and g(4).
f(4)=3(4)²+7(4)-3 [exponent]
f(4)=3(16)+7(4)-3 [multiply]
f(4)=48+28-3 [add]
f(4)=76-3 [subtract]
f(4)=73
g(4)=8(4)-5 [multiply]
g(4)=32-5 [subtract]
g(4)=27
Now that we have the value for f(4) and g(4), we can subtract them.
73-27=46
(f-g)(4)=46
