Answer:
7x - 7
Step-by-step explanation:
Variable: X = the unknown number
2x + (-7) + 5x
= 7x - 7
-1(3xy) = -1 * 3xy = -3xy
To vertically strech a function, f(x) by a factor of c, that is cf(x)
so strech vertically by 2 means times whole thing by 2
so
2 times (4x^2-5) =8x^2-10
g(x)=8x^2-10

Answer: the answer is 56
Step-by-step explanation: since the f(x) is -7 it would be 9 times -7 then minus 7 and get the answer.
