As it has a maximum value the coefficient of x^2 will be negative

The vertex will be at (-8,2)  so in vertex form it is

y = a(x + 8)^2 + 2
and as it passes through (-7,-1) we have:

-1  = a(-7+8)^2 + 2

-1 = a + 2  so a = -3

answer is  y = -3(x + 8)^2 + 2

in standard form this is y = -3x^2 -48x  - 190

Yes, because 1/4 plus 1/4 equals 2/4 (or 1/2) and 3/4-2/4 equals 1/4.

What is the x in 120(2x-2)=240
coldgirl [10]

Answer:

X=2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

120(2x−2)=240

(120)(2x)+(120)(−2)=240(Distribute)

240x+−240=240

240x−240=240

Step 2: Add 240 to both sides.

240x−240+240=240+240

240x=480

Step 3: Divide both sides by 240.

240x /240 = 480 /240

x=2

What is the range of the discrete finite function F(x)?
Whitepunk [10]

Answer:

Range = \{4,7,9\}

Step-by-step explanation:

Given

The attached function

Required

The range of the function

A function is represented by matching an arrow from the domain to the range.

This implies that, the arrow comes from the domain to the range

From the attached function, the arrow points to 4,7 and 9

Hence, the range is:

Range = \{4,7,9\}
