9514 1404 393

Answer:

  • a=50
  • b=45

Step-by-step explanation:

We can subtract the second equation from 4 times the first:

  4(a +b) -(4a +1.5b) = 4(95) -(267.5)

  2.5b = 112.5 . . . . . simplify

  b = 45 . . . . . . . . . . divide by 2.5

  a = 95 -b = 50 . . . find 'a'

The solution is (a, b) = (50, 45).

Which statements describe one of the transformations performed on f(x) = x2
posledela

Given:

The given functions are:

f(x)=x^2

g(x)=3(x+5)^2-2

To find:

The transformations performed of f(x) to create g(x).

Solution:

The translation is defined as

g(x)=kf(x+a)+b                .... (i)

Where, k is stretch factor, a is horizontal shift and b is vertical shift.

If 0<k<1, then the graph compressed vertically by factor k and if k>1, then the graph stretch vertically by factor k.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

We have,

f(x)=x^2

g(x)=3(x+5)^2-2

Using these two function, we get

g(x)=3f(x+5)-2                 ...(ii)

On comparing (i) and (ii), we get

k=3,a=5,b=-2

It means the graph of f(x) is vertically stretched with a scale factor of 3, shifts 5 units left and 2 units down to get g(x).

Therefore, the correct options are A and C.
