Answer:
B I guess is the answer
Step-by-step explanation:
I'm not really sure
20 is greater than y.
f(4) = 3×4^2+15
4^2=16
3×16
48+15
63
f(4)=63
a 6(m+3)
b expression
equation
Answer:10x^2 -18
Step-by-step explanation:since f(x) is becoming the new x then youd subtitute the equation into the x of the g(x) equation. which would be 5(2x^2 -5) +7 which is 10x^2 -25 +7.and you'd simplify from there.
