Question

The following graph describes function 1, and the equation below it describes function 2:

Function 1

graph of function f of x equals negative x squared plus 8 multiplied by x minus 15

Function 2

f(x) = −x2 + 2x − 3

Function ____ has the larger maximum.
(Put 1 or 2 in the blank space)

Answer 1

Answer 2

@Nnesha @pooja195

Answer 3

what is the maximum value for function 1?

Answer 4

15?

Answer 5

isn't function 1 the graph ?

Answer 6

Function 1

graph of function f of x equals negative x squared plus 8 multiplied by x minus 15

Answer 7

It says that so I said that but eh fine the graph

Answer 8

The largest number in the graph is 6

Answer 9

this graph

Answer 10

Yes that graph

Answer 11

that graph has a peak at y=1 (the highest it goes)

Answer 12

oh ok

Answer 13

the red line shows the max y value

Answer 14

and its one like you said

Answer 15

function 2 is
\[ f(x) = −x^2 + 2x − 3 \]
match this with
\[ a x^2 + bx+c\]
to see a=-1 and b=2
then figure out x= -b/(2a)

it has a peak at x= -2/(-2) = 1

Answer 16

Alright

Answer 17

we want to find the y value of the peak for function 2
we know that happens at x= 1 (see the above post)
put 1 in place of x in
-x^2 + 2x -3 to get
- (1*1) + 2*1 - 3 or
-1 + 2 -3
1-3
-2

the peak is at y=-2

Answer 18

which is higher (bigger) y= 1 for function 1 or y= -2 for function 2 ?

Answer 19

The first one Function One Thanks @phi

Answer 20

yes
