How the transformations of the functions f(x)=15tanx and g(x)=tanx+15 differ?
Irina-Kira [14]
The transformation of <span>f(x)=15tanx would be achieved by dilating y</span>=tanx graph 15 times. This transformation will cause y'=15 y. This will increase the value of dilation become 15 times of the original

The transformation of g(x)=15tanx would be achieved by shifting y=tanx graph 15 right. This transformation will cause x'=x+15. This will change the value from tan x into tan(x+15)

Find all values of x (if any) where the tangent line to the graph of the given equation is horizontal. HINT [The tangent line is
Nostrana [21]
By "y = −9x2 − 2x" I assume you meant  <span>y = −9x^2 − 2x (the "^" symbol represents exponentiation).

Let's find the first derivative of y with respect to x:  dy/dx = -18x - 2.  This is equivalent to the slope of the tangent line to the (parabolic) curve.  Now let this derivative (slope) = 0 and solve for the critical value:  -18x - 2 = 0, or
-18x = 2.  Solving for x,   x = -2/18,    or    x = -1/9.

When x = -1/9, y = -9(-1/9)^2 - 2(-1/9).  This simplifies to y = -9/9 + 2/9, or 
y = -7/9.

The only point at which the tangent to the curve is horiz. is (-1/9,-7/9).</span>

Evaluate (-A)^2 for A = 5, B = -4, and C = 2
drek231 [11]

Answer:

(-A)^2 for A = 5

(-5)^2

=25

Step-by-step explanation:

first, replace A by 5, and maintain the negative to the 5.

multiply (-5)^2.

nb: don't forget to maintain the bracket when multiplying. if you maintain the bracket, you'll get a positive number, but if you don't, you'll get a negative number.
