Answer:
<h3>
f[g(x)] = 4x²+6x-3</h3>
Step-by-step explanation:
- f[g(x)]=(2x)²+3(2x)-3...substitute the values of g(x) into the function f(x)
- f[g(x)]=4x²+6x-3...simplified

Answer:
32760
Step-by-step explanation:
This is a permutation of 15 objects taken 4 at a time. To calculate this, we use the formula:
![_nP_r=\frac{n!}{(n-r)!}](https://tex.z-dn.net/?f=_nP_r%3D%5Cfrac%7Bn%21%7D%7B%28n-r%29%21%7D)
In our case, n is 15 and r is 4:
![_{15}P_4=\frac{15!}{(15-4)!}=\frac{15!}{11!}=32760](https://tex.z-dn.net/?f=_%7B15%7DP_4%3D%5Cfrac%7B15%21%7D%7B%2815-4%29%21%7D%3D%5Cfrac%7B15%21%7D%7B11%21%7D%3D32760)
Did you figure it out yet? lol
