<u>Given </u>that the functions f(x)=x+4 and g(x)=x^{3}

We need to determine the value of the function (g \ {\circ} f)(-3)

First, we shall determine the composition of the function (g \circ f)(x)

<u>Function </u>(g \circ f)(x)<u>:</u>

Let us determine the function (g \circ f)(x)

Thus, we have;

(g \circ f)(x)=g[f(x)]

               =g[x+4]

               =(x+4)^3

(g \circ f)(x)=x^3+3x^2(4)+3x(4)^2+(4)^3

(g \circ f)(x)=x^3+12x^2+48x+64

Thus, the function is (g \circ f)(x)=x^3+12x^2+48x+64

<u>Value of the function </u>(g \ {\circ} f)(-3)<u>:</u>

The value of the function can be determined by substituting x = -3 in the function (g \circ f)(x)=x^3+12x^2+48x+64

Thus, we have;

(g \circ f)(-3)=(-3)^3+12(-3)^2+48(-3)+64

Simplifying the terms, we get;

(g \circ f)(-3)=-27+12(9)+48(-3)+64

(g \circ f)(-3)=-27+108-144+64

(g \circ f)(-3)=1

Thus, the value of the function (g \ {\circ} f)(-3) is 1.

What is the equation of the line that passes through the point (4, 3) and is perpendicular to the line x + y = 4?
zimovet [89]
ANSWER

y - x = - 1

EXPLANATION

The required equation passes through:

(4,3) and is perpendicular to x+y=4.

Rewrite the given equation in slope-intercept form:

y = - x + 4

The slope of this line is -1.

The slope of the required line is perpendicular to this line, so we find the negative reciprocal of this slope.

m= - \frac{1}{ - 1} = 1

The equation of the line can be found using:

y - y_1 = m(x - x_1)

We substitute the slope and point to obtain:

y - 3 = 1(x - 4)

We simplify to get:

y - 3 = x - 4

y - x = - 4 + 3

The required equation is

y - x = - 1
