Answer:

f(-2) = 0

f(1) = 12

f(2) = 5

Step-by-step explanation:

f(-2) will lie in the function f(x) =x^2 - 4

\therefore f( - 2) =  {( - 2)}^{2}  - 4 = 4 - 4 = 0

f(1) will lie in the function f(x) =2x^2 +10

\therefore f(1) = 2 {(1)}^{2}  + 10 = 2 + 10 = 12

f(2) will lie in the function f(x) =5

\therefore f(2) = 5

How to use exponents instead of logs
PSYCHO15rus [73]

Answer:

Convert into same base

Step-by-step explanation:

Convert both sides into same bases and equate the powers to solve for the variable.

Example:

8^x = 32

You can either use logs to bring the power down or convert both sides into the same base

8 = 2³

8^x = (2³)^x = 2^(3x)

32 = 2⁵

2^(3x) = 2⁵

3x = 5

x = 5/3

x = 1⅔
