Find g(x)-f(x). g(x)=x^2+1 and f(x)=2x+5

UkoKoshka [18]

Answer:

$g(x) - f(x) = x^{2} - 2x - 4$

Step-by-step explanation:

g(x) - f(x) = $(x^{2} + 1) - (2x + 5)$

Multiply the -1 in then add the two expressions together.

$(x^{2} + 1) + (-2x - 5) = x^{2} - 2x - 4$

URGENT I HAVE ALMOST 0 TIME LEFT I NEED LAST MINUTE HELP

jonny [76]

Answer:

The zeros are the points where the parabola intercepts the x-axis.

$\sf x = 7 \implies x - 7 = 0$

$\sf x = 1 \implies x - 1 = 0$

$\sf \implies y = a(x - 7)(x - 1)$ where a is some constant

If the parabola passes through point (3, 4) then:

$\sf \implies a(3 - 7)(3 - 1) = 4$

$\sf \implies a(-4)(2) = 4$

$\sf \implies -8a = 4$

$\sf \implies a = -\dfrac12$

So the equation of the parabola is:

$\sf y = -\dfrac12(x - 7)(x - 1)$

Or in standard form:

$\sf y = -\dfrac12x^2+4x-\dfrac72$
