Consider f(x) = 1.8x – 10 and g(x) = −4.
Pavlova-9 [17]

Answer:

Part 1) The equation that can be used is 1.8x-10=-4

Part 2) The input or x-value is x=10/3

Step-by-step explanation:

we have

f(x)=1.8x-10

g(x)=-4

To find the solution of the system of equations equate f(x) and g(x)

f(x)=g(x)

substitute

1.8x-10=-4 -----> equation that can be used  to find the input value at which    f (x ) = g (x )

Solve for x

Adds 10 both sides

1.8x=-4+10

1.8x=6

Divide by 1.8 both sides

x=6/1.8

Remember that

1.8=18/10

substitute

x=6/(18/10)

x=60/18

Simplify

x=10/3

Find f. f ''(x) = −2 + 24x − 12x2, f(0) = 7, f '(0) = 16
miskamm [114]
Integrate twice.

Remember the anti-derivative rule for polynomials:
\int x^n dx = \frac{x^{n+1}}{n+1} + C

f'(x) = \int (-2 +24x -12x^2) dx = -2x + 12x^2 -4x^3 + C \\  \\ f'(0) = 16, C = 16 \\  \\ f(x) = \int (16 -2x+12x^2-4x^3) dx = 16x -x^2 + 4x^3 - x^4 + C \\  \\ f(0) = 7, C = 7

Answer:
f(x) = 7 + 16x -x^2 + 4x^3 - x^4
