Answer:

A: $f(x)\leq -2$

Step-by-step explanation:

After graphing the equation, the highest point is (-1,-2). Since f(x) is the 2nd number in the coordinates (x, f(x)), the range is $f(x)\leq -2$

Answer:

Step-by-step explanation:

The graph decreases at first, then changes direction at (2, 5).

y = a(x-2)^2 + 5

Plug in (1,11) and solve for a:

11 = a(1-2)^2 + 5

a = 6

Equation in vertex form:

y = 6(x-2)^2 + 5

Answer:

37.5

Step-by-step explanation:

First you have to realize that these are similar triangles.

You can do a easy cross multiplication with these types of questions by forming an equation with the similar angles.

put the smaller above the decimal and the bigger one below like this.

$\frac{8}{25}$ = $\frac{12}{x}$

Now cross multiply

8x=300

x=37.5

Triangle DEF is an isosceles, so AngleDEF Is-congruent-toAngleDFE. A horizontal line has points C, F, E, G. 2 lines extend from

Answer:

$\angle CFD =105^o$

Step-by-step explanation:

Given

$\angle D FE = \angle DE F = 75^o$

See attachment

Required

Determine the measure of $\angle CFD$

$\angle CFD$ and $\angle DFE$ are on a straight line.

So:

$\angle CFD + \angle DFE = 180^o$ --- angle on a straight line

Substitute known values

$\angle CFD + 75^o = 180^o$

Collect like terms

$\angle CFD =- 75^o + 180^o$

$\angle CFD =105^o$
