1. For the quadratic function y = a(bx - c)2 + d, which of the parameter values (a, b, c, ord) will produce the transformation described?
horizontal stretch or compression
* a translation upward or downward
vertical stretch or compression
a translation left or right
For questions 2 - 7, describe what transformations of the quadratic parent function, f(x) = x?
will result in the graph of the given function.
2. g(x) = 2(x - 3)2
3. h(x) = -(x)2 + 5
1/+
4. g(x) = (4x - 7)
5.h(x) = 32
7. h(x) = 3(2x - 5)2 - 4
- 1
6. g(x) = -3(x + 2)2+6

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

step-by-step explanation:

no solution.
