Let f(x) be an exponential functionWhich transformations to the graph of f(x) would describe e - f(x - 3) ?
gayaneshka [121]

Look at the graph below carefully

Observe the results of shifting ={2}^{x}f(x)=2​x

​​  vertically:

The domain, (−∞,∞) remains unchanged.

When the function is shifted up 3 units to ={2}^{x}+3g(x)=2​x +3:

The y-intercept shifts up 3 units to (0,4).

The asymptote shifts up 3 units to y=3y=3.

The range becomes (3,∞).

When the function is shifted down 3 units to ={2}^{x}-3h(x)=2 ​x​​ −3:

The y-intercept shifts down 3 units to (0,−2).

The asymptote also shifts down 3 units to y=-3y=−3.

The range becomes (−3,∞).

WILL GIVE BRAINLIEST AND 30 POINTS. Solve the equation for x. Show each step of the solution. Name the justification for each st
lora16 [44]

Multiplication property of equality (Multiply both sides by 2)

9(8 - x) + 72 = 204 - 5(3x + 24)

Distributive property

72 - 9x + 72 = 204 - 7.5x  - 60

Combine like terms

-9x + 144 = -7.5x + 144

Subtraction property of equality (Subtract both sides by 144)

-9x ≠ 7.5x

No solution
