Find (f ∘ g)(-6) when f(x) = 9x + 2 and g(x) = -9x2 - 2x + 1.

Salsk061 [2.6K]

Given that the two functions are $f(x)=9x+2$ and $g(x)=-9x^2-2x+1$

We need to determine the value of $(f \circ g)(-6)$

<u>The value of </u> $(f \circ g)(x)$ <u>:</u>

The value of $(f \circ g)(x)$ can be determined using the formula,

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

Substituting $g(x)=-9x^2-2x+1$ in the above formula, we get;

$(f \circ g)(x)=f[-9x^2-2x+1]$

Now, substituting $x=-9 x^{2}-2 x+1$ in the function $f(x)=9x+2$ , we get;

$(f \circ g)(x)=9(-9x^2-2x+1)+2$

$(f \circ g)(x)=-81x^2-18x+9+2$

$(f \circ g)(x)=-81x^2-18x+11$

Thus, the value of $(f \circ g)(x)$ is $(f \circ g)(x)=-81x^2-18x+11$

<u>The value of </u> $(f \circ g)(-6)$ <u>:</u>

The value of $(f \circ g)(-6)$ can be determined by substituting x = -6 in the function $(f \circ g)(x)=-81x^2-18x+11$

Thus, we have;

$(f \circ g)(-6)=-81(-6)^2-18(-6)+11$

$(f \circ g)(-6)=-81(36)-18(-6)+11$

$(f \circ g)(-6)=-2916+108+11$

$(f \circ g)(-6)=-2797$

Thus, the value of $(f \circ g)(-6)$ is -2797

Hence, Option B is the correct answer.

The graph of a linear function passes through the points (-1, -1/4) and (1, -3/4). Which equation represents the function ?

lyudmila [28]

The equation of the line will be given as y = -4x - (- 17/ 4).

<h3>What is an equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Given that:-

The graph of a linear function passes through the points (-1, -1/4) and (1, -3/4).

The equation of the line will be given as:-

y - y₁ = m ( x - x₁)

slope m will be calculated as:-

$m =\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{1+1}{\dfrac{-3}{4}+\dfrac{1}{4}}=-4$

The equation will be:-

y - (1/4) = -4( x + 1 )

y = -4x - (17/4)

Therefore the equation of the line will be given as y = -4x - (- 17/ 4).

Which is the following have the correction solution? Select all that apply.

Mars2501 [29]

Answer:

(b) is correct.

Step-by-step explanation:

We substitute the given value of x in each equation and see if they fit.

a) 3x + 7 = 10 Plug in x = -1:

3(-1) + 7 = 4 so this solution is incorrect>

b) is correct because

5(5+4) - 5 = 45 - 5 = 40.

c and d are incorrect.
