F(x)=-2x^2 -5x+1 H(x)=3(x+3)^2-11

H(f(-1))=?

A.132
B. 136
C.140
D.144

B

Step-by-step explanation:

So we have the two functions:

And we want to find:

So, find f(-1) first. Substitute -1 into f(x):

Square:

Multiply:

Add:

Now, substitute this into h(f(-1)):

So, substitute 4 into h(x):

Add:

Square:

Multiply:

Subtract:

So, our answer is B.

And we're done!

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
