If f(x) = 3^x + 10 and g(x) = 2x − 4, find (ƒ+g)(x)

galina1969 [7]

Answer:

3^x+12x-4

Step-by-step explanation:

(f+g)(x) = f(x) + g(x) = 3^x + 10x + 2x - 4 = 3^x + 12x - 4

Can someone tell me how to approach this, I could care less about the answer I just want to know how to solve this without Desmo

kipiarov [429]

Answer:

the vertex is at (4, -14)

Step-by-step explanation:

Review "quadratic equations." These have three terms, and the highest power of x is x^2. We need to identify the coefficients of the x^2, x and x^0 terms to get info needed to identify the axis of symmetry.

Given f(x) = x^2 - 8x + 2, we see that these coefficients are 1, -8 and 2.

The formula for the axis of symmetry is x = - ------

which here is x = -(-8)/[2*1], or x = 8/2 or x = 4: the axis of symmetry.

To find the y-coordinate of the vertex, evaluate the function at x = 4:

f(4) = 4^2 - 8(4) + 2 = 16 - 32 + 2, or f(4) = -14.

Thus, the vertex is at (4, -14). The graph is that of a parabola that opens up, and the parabola is symmetric about the vertical line x = 4.

The equation of a straight line is y = 20 – X.

Reptile [31]

Given:

The equation of a straight line is

$y=20-x$

The x value of a point on the line is 14.

To find:

The y value of this point.

Solution:

If a point (x,y) lines on line, then the equation of line must be stratified by that point.

We have, the equation of a straight line.

$y=20-x$

Putting x=14, we get

$y=20-14$

$y=6$

Therefore, the y-value is 6 when the x-value is 14.

The expression, involving exponents , to represent the shaded area, in square inches, diagram. Then use that expression to calcu

mart [117]

Answer:

The shaded area is $23\ in^{2}$

Step-by-step explanation:

we know that

The shaded area is equal to the area of the large square minus the area of the two smaller squares

$A=6^{2} -(3^{2} +2^{2})\\ \\ A=(2*3)^{2} -(3^{2} +2^{2})\\ \\A=(2^{2})(3^{2}) -(3^{2} +2^{2})$

Calculate the shaded area

Remember that

$3^{2}=9\\ 2^{2}=4$

substitute

$A=(4)(9) -(9 +4)\\ \\A=36-13\\ \\A=23\ in^{2}$
