Question

Identify the domain and range of the function f(x) = -2x2 + 10x + 2.

Answer 1

Answer:

Step-by-step explanation:

range is the y values or ouputs

domain is inputs or x vvalues

we can use any x value

but at a certain y value, w can't go below that

find thatminimum

find the vertex

for

ax^2+bx+c

the x value of the vertex is

-b/2a

plug that in to the equaiton to get the y value

-b/2a=-(-6)/(2*2)=6/4=3/2

plug that in

2(3/2)^2-6(3/2)-9

2(9/4)-9-9

9/2-18

4.5-18

-13.5

domain=all real numbers

range=from -13.5 to positive infinity

mark me as brainliest

Answer 2

Answer:

Find the domain by finding where the expression is defined. The range is the set of values that correspond with the domain.

Domain: (−∞,∞),{x|x∈R}

Range: (−∞,∞),{y|y∈R}
