Three functions are given below: f(x), g(x), and h(x).
Rzqust [24]

Answer: The axis of symmetry is x=1.

Explanation:

The given function is,

g(x)=5x^2-10x+7

The degree of the equation is 2.  SInce it is a quadratic function therefore the graph of the function is a parabola.

The axis of symmetry of a parabolic function f(x)=ax^2+bx+c is a vertical line,

x=-\frac{b}{2a}

Since the value of a is 5m b is -10 and c is 7, So the axis of symmetry is,

x=-\frac{(-10)}{2(5)}

x=\frac{10}{10}

x=1

Therefore, the axis of symmetry is x=1.

Given that f(x) = 2x + 1 and g(x) = −5x + 2, solve for f(g(x)) when x = 3.
Mice21 [21]
I believe the answer would be -91 because if u solve both of the equations then the f(x) would be 7 and the g(x) would be -13 so it would be 7(-13) which equals -91.

What’s -2y+16=10 plz solve 2 step equation
konstantin123 [22]

Answer:

y=3

Step-by-step explanation:

To solve this 2 step equation, we need to get y alone. Lets write out the equation

-2y+16=10

Subtract 16 from both sides

-2y-16+16=10-16

Subtract

-2y=-6

divide both sides by -2

-2y/-2=-6/-2

divide

y=3
