F(x) = x2 + 3x + 2 is shifted 2 units left. The result is g(x). What is g(x)?

Misha Larkins [42]

Answer:

$g(x) = x^2+7x+12$

Step-by-step explanation:

If we are given a function f and we want to shift it a units horizontally, the resulting function will be f(x - a), where a positive a is a shift rightwards and a negative a is a shift leftwards.

We have the function:

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

And we want to shift it two units to the left.

Since we want to shift it two units to the left, a = -2. Therefore, our new function, let's call it g, must be f(x - (-2)) or f(x + 2). Substitute:

$g(x) = f(x+2)=(x+2)^2+3(x+2)+2$

Simplify. Expand:

$g(x) = (x^2+4x+4)+(3x+6)+2$

Combine like terms. Hence:

$g(x) = x^2+7x+12$

Write the equation of the line passing through the point (a, b) and having a slope m.

allochka39001 [22]

The equation of the line is b = am + c

<h3>What are linear equations?</h3>

Linear equations are equations that have a constant slope, average rate of change or gradients

<h3>How to determine the line equation?</h3>

The point is given as

(x, y) = (a, b)

The slope is given as

Slope = m

A linear equation is represented as

y = mx + c

Where me represents the slope

Substitute (x, y) = (a, b)

b = am + c

Hence, the equation of the line is b = am + c

the sitting height (from the bottom of the seat to the top of the person's head) of female drivers is normally distributed with

Sindrei [870]

Answer:

B; 50%

Step-by-step explanation:

Here, we want to calculate the percentage of women that will not fit in the driver’s seat

We proceed as follows;

We start with calculating the z-score of this;

That would be ;

(x-mean)/SD

in this case;

x = 34 inches

mean = 34 inches

SD = 1.4 inches

Thus, we have that;

(34-34)/1.4 = 0/1.4 = 0

when z-score is 0, we are at the center of the distribution

A z-score of 0 corresponds to exactly 50%

Find the measure of angle b. your answer_____

Sladkaya [172]

Answer:

b = 131

Step-by-step explanation:

The two angles form a straight line so they add to 180 degrees

b+49 = 180

Subtract 49 from each side

b = 180-49

b =131
