tatuchka [14]

Answer:

Domain = 1,3,5,7

Range = 8,7,6,5

Step-by-step explanation:

We need to identify the domain and range of the function: input 1,3,5,7 output 8,7,6,5

Domain of function:

For any function domain is set of input values.

Range of function:

For any function range is set of output values.

So, for the given function we have : input 1,3,5,7 output 8,7,6,5

Domain = 1,3,5,7 (set of input values is domain of function)

Range = 8,7,6,5 (set of output values is range of function)

Vikki [24]

Answer: (c)

Step-by-step explanation:

Given

The expression is $3x^2-7$

checking options, for (a)

$\Rightarrow 2x^2-11-x-4\\\Rightarrow 2x^2-x-15$

option (a) is incorrect

for (b)

$\Rightarrow 5x^2-6-2x^2+1\\\Rightarrow 3x^2-5$

option(b) is incorrect

for (c)

$\Rightarrow 10x^2-4-7x^2-3\\\Rightarrow 3x^2-7$
