Answer 1

Answer:

Answer:

7 + 3² - 2.5 / 4 - 1.2 > ( 3/4 + 1/8 ) ÷ 1/8 - 2²

Step-by-step explanation:

7 + 3² - 2.5 / 4 - 1.2 = 4.82142857

( 3/4 + 1/8 ) ÷ 1/8 - 2² = 3

Which means :

7 + 3² - 2.5 / 4 - 1.2 > ( 3/4 + 1/8 ) ÷ 1/8 - 2²

A graph of a parabola with x intercepts of negative 0.5, 0 and 2, 0 and a vertex of 0.5, 4 is shown.

Which function has a larger maximum? Type your answer as 1 or 2.

Answers

Answer:

The function 2 has a larger maximum.

Step-by-step explanation:

The vertex form of the parabola is

$f(x)=a(x-h)^2+k$ .... (1)

Where, (h,k) is the vertex.

The given functions are

$f(x)=-3x^2+2$ ..... (2)

Since the leading coefficient is negative, therefore it is a downward parabola. It means the vertex of the parabola is the maximum point.

On comparing (1) and (2), we get

$h=0,k=2$

Therefore the maximum value of the function is 2 at x=0.

The second function has x intercepts of (-0.5, 0) and (2, 0) and a vertex of (0.5, 4).

It is also a downward parabola because the parabola has two x-intercepts and the vertex lies above the x-axis.

Since the vertex is (0.5, 4), therefore the maximum value of the function is 4 at x=0.5.

$Maximum(F_1)=2$

$Maximum(F_2)=4$

Therefore function 2 has a larger maximum.

Answers

all of them involve y intercepts

f(x) means y
g(x) means y

y intercept is where the graph crosses the y axis or when x=0 so set x=0

f(x)
x=0 when y=-7.5
y int=-7.5

g(x)
x=0
set x=0
y=3^0-7
y=1-7
y=-6

f(x) yint=-7.5
g(x) yint=-6

A. y int of f(x) is less than yint of g(x)
-7.5<-6
true

B. this is oposite of A so this is wrong

C. this says that g(x) has no yint, false

D. they yints are eqla
-7.5=-6
false

answer is A

Answer:

f(x)

x=0 when y=-7.5

y int=-7.5

g(x)

x=0

set x=0

y=3^0-7

y=1-7

y=-6

f(x) yint=-7.5

g(x) yint=-6

A. y int of f(x) is less than yint of g(x)

-7.5<-6

true

B. this is oposite of A so this is wrong

C. this says that g(x) has no yint, false

D. the yints are equal

-7.5=-6

false

answer is A
